V1.7
-Updated to patch 1.7
-Raised impact for going over the naval forcelimit from 1 to 2 (now same as for land forcelimit, going over forcelimits should not be profitable and AI doesn't do it)
-Lowered peace cost for demanding trade power from 60 to 30 (old value, 60 is too much for too little impact)
