Animated doors

[cxong]

Doors open and close instantly. Can a subtle animation be added, showing the door sliding in/out?

It may even be possible to do this without introducing new graphics, just fancy blitting.

Now that we have bigger doors, sliding isn't too appropriate. We may have to animate the doors sinking into the floor instead.

Therefore, it's best to do this with replacement graphics.

#430 was done recently, so this can be implemented via animations. Maybe the same animation played in reverse can be used for opening/closing.

However, doing so will require reworking the door graphics and drawing system. The vertical door graphics are too short to animate. The open door sprites should be combined with the close door sprites so that one animates into the other.

If we edit the door sprites to support wider doors (#474), we could still animate sliding. For example, a 2-width door could slide from both sides into the middle.

I wonder if different doors should have different animation types?
