Be warned, support for QT6 remain untested. Fixed up build.py
to be forgiving if some lib files are missing. Removed the use
of QRegExp since it has been deprecated.
linux_build.sh is now replaced by the build.py and install.py Python
scripts. with this comes cross platform build/install support
between Windows and Linux.
as of v4.x.2.x of the MRCI protocol, the TEXT type id is now
formatted in UTF8 instead of UTF16LE unicode. this change also
affected the tcp rev and several async commands so client code had
to be ajusted accordingly.
