More fun with state machines!

The only information stored about any grid location is the number for the sprite that's in it -- which means I can save the map in less than a byte per square!

The tools each have a lookup table of what sprites they turn other sprites into, and any tile type can have a function which takes its four neighbors as inputs and optionally yields a tile to turn into.

(The hole sprite is silly but I need to make some variants for it to display right.)
