Image.c
* moved to getseters (use new generic ID funcs)
* added 'reflect' attribute
Text.c
* moved to getseters (new generic ID funcs too)
NLA.c
* moved to getseters (ditto)
Ipo.c
* bugfix, allow nested loops on an IPO's curves.
Blender.c
* removed undocumented function RemoveFakeuser, since actions now have the fakeUser attribute.
