Version 0.9.9.6 - A cool new game mode idea

The new campaign mission is different from all other missions yet.

*Spoiler*
You can't build in this mission and you have only a few units to destroy all spawners.
This one is really hard on high difficulties but it is definetly possible.

*Spoiler*

Please let me know if you like it, I might add this as a seperate game mode later.

Mechanics:

-New campaign mission: Icy pass
-New spawner: Ice spikes
-New Enemy variation: Snow Wolf
-New Enemy variation: Polar Bear
-The monk does now have his own symbol when selected
-There is now an indication if a unit is buffed by a monk

Balancing

-Decreased the Ice Golems health, atk and defense

Bugfixes:

-The player had to have 1 more gold to skill then it was displayed
-The bear made weird sounds when walking
-The players stat window did not show when having max level
