CrystalV1

Here I'm mostly testing out how custom promeshes react to... everything. I've learned a few things.

1) The diagonal in the entire promesh is used as an axis of rotation, so you had better design your meshes with that in mind or you'll get gaps.

2) Blood red is a bad fog color to use when testing.

Also, this is nowhere near the final design for the Crystal biome's promesh. There will be more crystal and less white rock in it.
