Bounded camera

[zorfmorf]

We need the camera to move with the player. However, it should not be centered but instead there should be some kind of sqaure in the center and the camera only moves if the player reaches the square borders.

I bound the camera to the player position which was easy. But we probably want some sort of map boundary definition where the camera never moves over it. This would have to be defined in the editor

Done!
