Health bars & Bots & UI fixes

We have finished the health system! Players now have 5 hearts (10 health points) which can be substracted. In addition if a player loses all hearts, he'll die. Also we have implemented bots and made a few new ui elements (like the player overview on the bottom right).

The health icons are not yet ready so there are currently only red squares :owl:

Our first two special field types are also (technically) ready: The spike field and the hospital. The models will also be ready soon!
