Modpack refactor (#4)

Split this mod into a set of sub-mods in a modpack, and in the process did a whole bunch of renovations.

* updated Subterrane's API to allow for more patterned placement of things
* added "warrens"
* clean separation of flooded and non-flooded caverns
* rearranged biomes to make cavern layers more distinct
* added oil layer
* added underworld layer

+Minetest Game mod: ice_sprites
+============================
+Adds ice sprites, which can then be caught in a net (via the fireflies mod) and placed in bottles to provide light (via the vessels mod).
