changed the default installattion used in the linux_build.sh
script to create an installer that deauly installs the
application data files in the /var fold folder instead of
the user specific folder in /home.
also made it so it will now create a system user named after
the name of the application and use that user to run the
systemd service instead of the currently logged in user.
doing this harded system security by having the application
run as an under privileged user. this also opens up the
possibility to lock down direct writing access to the host
database to just the internal module (in a future update).
removed the -start command line argument and have just the
-host option to start new host instances. the -start option
would start the host as the current user so i decided to
remove it as a way to encourage end users to start/stop the
host via systemd.
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.
-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.
Moved away from QPluginLoader to C/C++ style QLibrary files for the
module interface. It's less limiting this way because the host can
be built statically and still beable to load non-statically built
modules. It's not tested but the i think it should now beable to
load modules built on a different version of Qt than the host but
the module would must likely need to be build statically.
Another change to the module interface makes it so the module can
can now also see the host version in CommandLoader::hostRevOk()
and decide if the host can continue loading it.
The host 'host_info' internal command now displays the version of
Qt it was built on.
All documentation related to the module interface has been
updated. No attempt will be made at the host side to support rev
2 modules so the new minimum rev is now 3.
1.0.2 --> 1.1.2
