Propagate Pose Tweaks:
- Renamed "Last Keyframe" mode to "Before End". This mode still just
copies the pose to all keyframes starting from the current frame until
the last one encountered per F-Curve
- "Last Keyframe" mode (new one) now copies the pose to the last
keyframe. This is useful for making animations cyclic (i.e. go to
first keyframe, edit, then Pose->Propagate->To Last Keyframe (Make
Cyclic))
