- Blender.Window: added function GetPerspMatrix() (Tom Musgrave's patch, thanks);
- added Chris Want's patch to tell argc, argv to the Python interpreter (thanks, Hos);
- Blender.Image: added image.glFree() to free textures bound by the recently added
  image.glLoad() (both suggested by Campbell Barton -- thanks, with these Blender can
  be used to load textures for scripts);
- Blender.Sound: removed for now at least a few get/set methods of vars that can't be
  accessed via interface;
- renamed Get/makeActive to Get/setCurrent in Blender.World (actually added alias for
  now), same in Blender.Sound: renamed makeActive to setCurrent.  Stephen Swaney
  pointed this some weeks ago, we should stick to one naming convention.
- added documentation for Sound and Window.Theme modules and the other added
  functions, made other small updates.
- Blender.Object: made 'worldspace' become the default output of .getMatrix and .mat/.matrix:
  after reading a discussion on blender.org's Python forum where eeshlo mentioned the
  pre 2.34 default was worldspace, I took a better look at Blender's relevant code,
  confirmed, talked to Theeth about this and as he suggested am changing the default
  back to 'worldspace'.
