Broke animations, almost feature-complete though

- Animations don't work anymore. Should be a simple fix, but I made some
  changes in checkRemove that fix the crazy spinning bug.
- Still get three-in-a-rows generated randomly sometimes after removals,
  but they don't break anything at least.
- Bottom-right 4 blocks are ZZZ blocks which you can only swap with if
  you're Kosbie and are adjacent to them. Then you win. Don't have any
  code for showing off you won though.
