Add LBMs, ABMs, and more
This commit adds 1 new LBM (for foliage) and 2 new ABMs (one for foliage, and one for grass). This also adds a new generator so any new maps created will have biome coloured leaves with a faster method. (Vines are excluded from this generator since I don't know yet how to get those to work with this.)
