Digimobs

There's always a bugfix.

Specifically, to address a crash and some issues with older model formats not recognizing Dot Mode.

I've also added a new config option to allow Digimon with only sprites to spawn in the world, if people want -everything- to spawn.

And this is mostly because I was already working on adding Digimon and not planning on a bugfix, so enjoy a couple of new armor digimon in sprite only forms I suppose!
