c8f53d1e5c Slimmed down and simplified host administering
- I decided to remove the entire concept of a root user.
  Instead, the host initializes as a blank slate and it
  will be up to the host admin to create a rank 1 user via
  the new command line option "-add_admin" to do initial
  setup with.

- There is no longer such a concept as a protected user.
  Meaning even the last rank 1 user in the host database
  is allowed to delete or modify the rank of their own
  account. To prevent permanent "admin lock out" in this
  scenario the "-elevate" command line option was created.

- Host settings are no longer stored in the database.
  Instead, host settings are now stored in a conf.json file
  in /etc/mrci/conf.json if running on a linux based OS or
  in %Programdata%\mrci\conf.json if running on Windows.

- Email templates are no longer stored in the database.
  Instead, the templates can be any file formatted in UTF-8
  text stored in the host file system. The files they point
  to can be modified in the conf.json file.

- The conf file also replaced all use env variables so
  MRCI_DB_PATH, MRCI_WORK_DIR, MRCI_PRIV_KEY and
  MRCI_PUB_KEY are no longer in use. SSL/TLS cert paths can
  be modified in the conf file.

- Removed email template cmds set_email_template and
  preview_email.

- Also removed cmds close_host, host_config and
  restart_host. The actions these commands could do is best
  left to the host system command line.

- The database class will now explicitly check for write
  permissions to the database and throw an appropriate
  error message if the check fails. "DROP TABLE" SQL
  abilities were added to make this happen.

- Removed async cmds exit(3), maxses(5) and restart(11).

f62eb125cf Added Windows Build/Install Support
- added a -host_trig command line option that creates a new host
  instance without blocking user input.

- the build/install python scripts will no longer internally build
  platform specific shell scripts; instead, they will now copy the
  necessary templates from the /templates folder.

- modified both build.py and install.py to include windows
  deployment support so this app can now be built/installed on
  windows based host. note: i decided to have it "daemonized" as
  a scheduled task that runs on system start instead of service
  because it is simply easier to do it this way and will not
  involve any 3rd party libraries or apps.

- added the src/applink.c file to the source code since it is
  needed for windows openssl support.

- changed over all references of "endl" to "Qt::endl" to avoid
  depreciation errors/warnings.

6e068a8e83 New versioning system, type ids and a few bug fixes
Changed the versioning system to a 4 number system that have the first 2
numbers as major.minor for the host application itself and the next 2
numbers (tcp_rev.mod_rev) used by clients and modules to determine
compatibility. A full description of this new system has been edited
into protocol.md. This new system offically starts at v3.0.0.0.

Added the PROMPT data type id that will work exactly like PRIV_TEXT except
it tells the client that the command is asking for non-private information
from the user.

Added PROG and PROG_LAST type ids that can be used by commands to notify
the client of the progress of the command if it is long running. The
long running fs_* commands were updated to use these instead of TEXT for
progress updates.

PUB_IPC, PRIV_IPC and PUB_IPC_WITH_FEEDBACK have all been combined into
one: ASYNC_PAYLOAD. This type id is now the only means at which module
commands can now run async commands. The command process object will
now determine where to direct the async payload (public, private or
public with feedback) based on the async command id being requested.

A description for TERM_CMD was missing in data_types.md so it was added.

Refactored HALT_CMD to YIELD_CMD. The new name just seems more appropriate
or the effect it has on the command.

Module commands can now do input hooking using the new ASYNC_HOOK_INPUT
and ASYNC_UNHOOK async commands. input hooking basically makes it so all
client data gets redirected to the module command that initiated the hook.
This can be used to implement something like a EULA agreement that blocks
all actions that can place during the session until the user accepts or
anything else to that effect.

The command process object will now check the open sub-channels list
being sent by ASYNC_CAST or ASYNC_LIMITED_CAST in any order and will not
be required match exactly to open sub-channels list in the session object.
It however cannot contain sub-channels not already listed in session's
list or else the async payload will be blocked.

Fixed the CmdProcess::validAsync() function that was comparing the input
aysnc command id with the process's command id in some places which is
invalid logic for this function.

Fixed the 'cast' core command that was outputting a malformed async
payload that didn't include the open writable sub-channels list.

Fixed a bug that caused all casted payloads to be forwared to the clients
even when the sub-channel(s) are closed.

Fixed the 'set_disp_name' core command so it can now see the -new_name
argument properly.

4c1d13f8f8 Password and account security updates
security updates:

various commands that change or create account passwords now disallow
the user name, display name or email from being contained in it. this
will force users to not use public information inside the password,
hardening password security a little.

the root user name is now changeable and required to be changed on
initial login. this harden security a little by giving host admins the
option to not have a well known user name attached to a high privileged
account.

users can no longer re-use the old password and/or user name when
required to change. however, this does not actually implement full
password history because the user can then later change the password
back to the old password after the required change.

the host can longer block by ip addresses and the auto block threshold
setting has been removed. something like this is best left up to
firewalls, routers, switches or any other networking infrastructure. in
the future i can consider adding event triggering that run certain
admin defined external or internal commands when the host detects
certain event thresholds.

minor changes/bug fixes:

all commands that change or create user names now no longer accept
user names that looks like an mail address. this works out better for
clients when differentiating logging in via user name or email address.

the recover_acct command now also have cancel on blank text options
making it more consistent with all other commands that take text input.

resetting the root user's account password via command line now also
unlocks it if locked.

the -help and -about command line options no longer display the
default password. a new -default_pw option was added for this purpose.

the -status -addr or -stop command line options require super user
privileges to run properly depending on how the host is installed.
an error message like "permission denied" was addded on failure to
make this requirement clear to the end user.

fs_copy and fs_move now does implicit skip on error instead of stop on
error.

the IDLE frame type id now carry an integer return code that can be
interpreted by clients to determine the result of the command that was
sent to the host.

house keeping:

all documentation was updated to reflect the changes made in this commit.
the module tester example is no longer relevant to this project so it
was deleted.

f6ea7239a0 Further updated the documentation and a minor fix
fixed some errors found in the documentation and fully updated the internal
commands docs as well.

also updated the internal module to now respond to KILL_CMD so it can now be
signaled to terminate gracefully.

e7ea316bc0 Full documentation update and minor changes
-the add_mod command now requires the -mod_path argument as it should.
-the session now filter out bad NEW_CMD frames based on bad command names and incorrect
 frame sizes.
-modules running in list mode can now send ERR frames to the session to log error
 messages to the host database.
