Added compatibility for QWinWidget and QMfcApp 

Hi!  Thanks for putting this repo together, it was super helpful in understanding how SIP works.  I made some modifications to the files in order to get the WinMigrate module to compile for me, as well as being compatible with the requirements from Blur's 3dsmax Python plugins (we couldn't use the version they supplied, as our python versions were different..).

Feel free to take my changes if you wish.

- Changed out module name to QtWinMigrate (ie. from PyQt4 import
QtWinMigrate)
- Added basic wrapper for QMFcApp class
- Added wrapper for QWinWidget class
- including manually generated moc_*.h files for necessary modules
