Bug fixes and optimizations for Vanilla 1.7.10 and a few mods.

Backport mod for 1.7.10, porting content from modern versions. Continuation of the old Et Futurum mod.

The goal of this mod is to expand upon the vanilla game in every aspect, overhaul all vanilla biomes, the Nether, the End, and add brand new late game features without striving to far from Vanilla.
