[Development] Qt Playground - Command Line Parser experiment

[shane.kearns at accenture.com]

I would like an argument parser in Qt, and I'd like it to be in qtbase.
The reason for qtbase is so that our own tools and manual tests can use it.
Manual tests outside of qtbase are normally GUI based.

I think this is something that can go into a minor 5.x release.

About windows:
Tools that use / for arguments also accept - (except the built in shell commands)
The / can be used for both short and long arguments (e.g. "nmake /nologo" vs "nmake /kc" vs "nmake /k /c")
Arguments may be case insensitive

The command line is pretty much only used by technical people (buried 3 levels deep in the app menu), who would probably accept unix style args.

If we want to support windows style:
Use Qt::CaseInsensitive to opt in to case insensitive args
Print a qWarning if the arguments could be ambiguous (assuming the API declares the possible arguments up front like perl's GetOpt::Long)
Allow opt out from short argument compression (i.e. "/xzf" would only be considered as a synonym for "--xzf" and not for "-x -z -f" if the opt out is applied)
