All features (tendrils, canyons, ...) can now have their own material modifiers.
Sphere generator. But not functional yet
Temporarily blacklisted 'spheres' feature because it is not implemented yet.
Added support for 'mob' dimlets and added a bunch
Nicer output
Added a new dimlet type called 'Special'. This is reserved for special style (and usually very rare) dimlets that don't fit in any other category.
Added a new and expensive 'peaceful' dimlet that disables hostile mob spawning (except for the mobs that you put in yourselves).
Implemented a very rare 'efficiency' dimlet that adds a 20% reduction to maintenance RF/tick
Prevent RF/tick from going below 10.
