Build 26510362

Archers now switch to meele if they run out of arrows or if an enemy meele unit is too close.

Cities now need to be captured by scaling the walls on ladders. The player can choose what wall he wants to attack by pressing Middle Mouse Button on a green wall. Units will then mount ladders there. If ordered to attack with Arrow Up all selected units will start scaling the walls. The enemy also deploy ladders and scale walls if you are defending.

Added procedual cleanup of corpses and arrows. This helps performance during large battles.

Max units on the battlefield at once is still 100 for performance but both side gets reinforcements if they have more troops to draw from once the current wave is wiped out. Campaign Troop limit with maxed out Leadership skill is now 300 instead of 100.
