Make Qt Quick Widgets Mac specific. Apparently its so new the Qt folks have not figured out cross platform config entirely yet

Also added Qt version check.
And made the platform/toolchain check a little more descriptive.

Fix HIL link reconnect issues due to missing threading flag usage, warn user about missing config and take him to config view if necessary

Fix HIL link reconnect issues due to missing threading flag usage, warn user about missing config and take him to config view if necessary

Recent threading changes have broken both of these. They will be fixed
in a separate pull request. Also added new CmdLineOptParser.cc/h

Ignoring for now and I’ll work on fix in a separate pull.

Also changed WarningsAsErrorsOff to WarningsAsErrorsOn to be used by
TeamCity builds.

Figured out why command line builds were not working. To build Windows
release from command line you need msbuild …
/property:Configuration=Release

No idea why, but manipulating CONFIG inside the build file confuses
msbuild command line builds. Work fine if you build from the IDE!

Not going to fix these two warnings in Windows builds so silence from
makefile

Makes sure all Windows code interfaces nicely with Qt. Also required
for utils and qupgrade libraries to compile.

Number of warnings is low enough now to let them come through. Lowered
Windows warning level the /W3 to be more consistent with OSX/Linux
level of warnings. Removed /WX from Windows build. I’ll put it back
once everything is cleaned up.
