Room based camera

Hi all,

I've made a change so that the camera is focused on 1 room, when you move into another room, the camera changes focus onto that room. In the long run the room transitioning will be smoother, like in 2D zelda games.

My next task I'm going to focus on is getting monsters spawning when you enter rooms, and restricting room access with win conditions. For starters, you must kill all monsters in the room to progress to the next. Later on other things may happen instead, like completing the puzzle in the room to progress.

Below is a screenshot of the new camera positioning. A minimap and inventory HUD will be eventually added, not sure exactly where those should go, and any input would be appreciated.
