Patric Stout f05e2e0d40 Feature: allow setting a custom terrain type to define highest peak
At least, TGP will try to reach it. It heavily depends on the map
if it is reachable at all. But for sure it will do its atmost to
get there!

* In randomly generated maps:
* TROPICZONE_DESERT: Generated everywhere, if there is neither water nor mountains (TileHeight >= 4) in a certain distance from the tile.
* TROPICZONE_RAINFOREST: Generated everywhere, if there is no desert in a certain distance from the tile.
* TROPICZONE_NORMAL: Everywhere else, i.e. between desert and rainforest and on sea (if you clear the water).
*
* In scenarios:
* TROPICZONE_NORMAL: Default value.
* TROPICZONE_DESERT: Placed manually.
* TROPICZONE_RAINFOREST: Placed if you plant certain rainforest-trees.
