Add Mouse controls

[Logicon211]

Left click to select, right click to tell where to move (Pathfinding later? Just move left and right for now). Basic stuff for now

Right clicking to tell where to move is actually gonna be a little wierd. Will need to figure out where in map space you clicked. Am I going to find the exact pixel point we want to move to? Or am I going to try and figure out the maptile to move to.
