Re: wxPython 4.1 support

All current branches should now be compatible with 4.1.
The Layout -> Alignment flags will be adjusted on loading and editing.
The side effect is that flags like wxALIGN_RIGHT may get lost when you 
change the containing sizer e.g. from vertical to horizontal and back to 
vertical again. I will probably improve this, but only for a 1.0 
release, not for 0.9.x.

Please test and give feedback if there are any problems.
After some testing, I will upload a 0.9.6 release.

Dietmar
