- 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
