MapGenerator Massive Update

Map Generator now uses a more biome based generation system. This gives
the map a more real feel by having similar tiles near each other. Also
modified the Mountain. They now generate in strips with random twist and
turns and have a thickness.

Possible future features:
Longitudinal based generation chance
Additional Biomes
Biome Size based off biome type
Biomes of certain types not appearing near each other (water near
desert)
