Disable enemy generation

TREES ARE THE NEW ENEMY no 1! Enable mod to disable the spawning of enemy bases and trees on NEWLY GENERATED chunks. Disable mod to restore previous behavior. This way you can go mega without having to use lua commands (=losing achievements) or restart the game and can actually kill all enemies. WARNING: Usually the game generates a few more chunks than what the player sees and enemies may already have been generated and exist on chunks not yet discovered by the player and may expand.
