Fixed the display of the healthbar.
Fixed pathfinding, also a problem because of the new settings location. Everything is fixed now!
Fixed "//TODO: Update documentation on this function".
Documented some properties of the Map object.
Added a new skeleton function to the enemy factory.
I'm now using the same function to generate normal, medium and hard rooms.
Added code to fill hard rooms with skeletons.
A map now holds an array with all hard rooms.
These settings aren't used here anymore, they are stored in a map.
Restored the old tilesize!
