Character movement map slide animation

[tlhunter]

When a character moves, there's a delay between when they can move again.

This makes sense for classic gameboy / NES / overhead games (think Zelda and Pokemon). Specifically why it makes sense is that the screen is animating between the old state and the new state.

Unfortunately it feels buggy in CC3 due to this lack of animation. Add the animation and we should be A-OK.

This will likely be made moot by #23...
