AOM Defensive MOD 1.1 file

Description:
A lot of players, me inclusive, like the ability to sometimes play a defensive role. To do this every Ruler needs strong walls and towers, what the original game lacks. This MOD changes the strongness, costs and buildtimes for towers and walls. It makes them much stronger but in the same time the strong ones need longer to be build and repaired and it costs you more resources. In addition the costs for upgrading walls and towers are raised too. Costs and buildtimes now vary between the several types of one of these buildings and their upgrades. In the original game it does not depends if you build a Watch or Guard tower for exmaple, the cost and buildtime was everytime the same. Another thing in the original Game, to build "Wood Walls" without the need of wood, what is a little bit curious in my eyes, is changed with this MOD too.
