[wxMac] More compile changes

OK, I removed the fragment= section from the line that was giving me errors with SWIG, and while I'm not sure if that was a good thing or not, it is at least letting me compile. =) Here are the things I've noticed so far:

- wxWindowVariant enum in _window.i should no longer have wxWINDOW_VARIANT_DEFAULT as it is no longer in include/wx/window.h

- Get/SetMacTheme in _brush.i should become MacGet/SetTheme

- In wxPython/contrib/gizmos/treelistctrl.cpp at line 4210, the #ifdef __WXMAC__ code can be removed. Update does the right thing now. =)

After doing these things, I was able to get wxPython building and running with CVS HEAD. =) Overall, it does work well. There are some graphical glitches, but only a few were showstoppers (crash, freeze). I'm going to report the major ones on wxDev and in most cases I think there are simple fixes. Once I get the message out on wxDev I'll try and spend a little time giving 2.5.1.4 a workout.

Thanks,

Kevin
