Lattices now have AnimData

This allows manual (point by point) animation of their control verts,
although many other settings cannot really be animated with any
visible effects yet. Interestingly, lattices also had IPO block
pointers, though they were never really used (AFAIK).

Todo:
- Animation Editor support has yet to be added. I've got a few other
things to add to, so will group those changes together.
