Mechanics:
-New campaign mission: "Vikings" (Thanks to Jevgeni for creating this nice map!)
-The church makes the villagers happy now (0-18 villagers = 3 happieness, 19-33 villagers = 2 happieness, > 34 villagers = 1 happieness)
-New head: Ogre Tamer Head (Get this by getting the achievement for destroying his castle)
-Observation tower, woodcutter, chickenfarm and the normal gate house do now have arrows to indicate the direction
-The observation tower can be rotated now

Balancing:
-Increased the taxes to 20g per tick (before it was 15g)
-The player does now get taxes on happieness rank 0
-Beer, wool and cloth are now worth less at the market
-Trees grow a little bit faster now
Bugfixes:
-The spawner in the tutorial was facing the wrong way
-The rock can't spawn in the center of the map anymore (player getting stuck)
-Trees could still spawn on top of water in some cases
-Builders got stuck if they got teleported when not using their resource
