Some semi-random thoughts on terrain generation

[xoft]

I think I'll remodel the generators a bit. I'm concerned with lava-filling the caves. Not everyone likes lava and it's a bit awkward to implement that fill in each and every cave generator we have. So I'll remove it from there, the caves will only hollow out the ground. And I'll add a lava-fill finisher with a settable lava height level. Makes more sense
