*python additions
- added a method Action.getFrameNumbers()
returns the frames at which keyframes were inserted for this action

example usage:
import Blender

myobj = Blender.Object.Get('Armature')
myaction = myobj.getAction()
frames = myaction.getFrameNumbers()

for frame in frames:
print 'bones at frame %d' % frame
myobj.evaluatePose(frame)
pose = myobj.getPose()
for bone in pose.bones.values():
print bone.head, bone.tail
