Climate Control/Geographicraft

0.8.7 Fixed a startup crash

          Added a config, extremeClimateSeparation, which if set to true increases separation between different climates. Contacts between climates 2 zones away such as Taiga-Desert should become extremely rare. However, hot and Snowy climates will become less common and smaller on continents. Note that according to vanilla Jungle and Extreme Hills are both in the Warm zone so a lot of odd junctions involving those biomes are perfectly legal and not affected by this setting.  Jungle-Ice Plains and Jungle-Cold Taiga *will* be blocked.
