- `Tileset.animation_slowdown` is gone!
- Actors are now free to animate every move or every two moves, and have
been configured to do so appropriately. This fixes the appearance of
blobs, most noticeably. (Also fixes #36.)
- Actors that are always animated in CC2 are now always animated in LL.
- Lilypads/turtles now bob randomly. More randomly than CC2, even.
- Players no longer appear to be swimming when stepping off of lilypads.
- Invisible walls no longer temporarily reveal themselves when you have
the x-ray glasses (secret eye).
- There's a new option for using the CC2 animation timing, though god
knows why you would want to.
