Very early start of `Inherited values`, simple replacement...

Similar to what is described in this post:
http://dev.bukkit.org/bukkit-plugins/terrain-control/forum/55872-terrain-control-2-5/#p10

Also, for certain feature items, I will be testing with feature flags in
the plugin configs so that development on the same branch isn't as
intrusive into what others are doing :D We shall see how it goes!
Addition of apache commons lang3 and junit libs
Merge branch 'feature-BioInherit-VirtBiomeId' of https://github.com/Wickth/TerrainControl into feature-biome-inheritance
