New user interface

I've been working on a new user interface, sice the last one was really not that good.

It takes a lot of influence from Company of Heroes and C&C Generals. Here's a picture with no unit/structure selected:




And here's another one with a structure selected. The build-buttons -class renders all the available build options on the free slots on the interface. The build-buttons -class works together with the gameMouse -class to test if the button in beeing hovered.




I'm much more pleased with this new interface than with the old one, but making these cosmetic changes is newer a wise thing to do when theres still a whole lot of the game engine missing...
