Updated Grid and Repels

Not sure why it's not letting me commit a scene but in the game, if
things look weird because of the new grid size, change the size to be
960x880. Change the camera x = 5.5; camera y = 4.5, grid x = 4.5; grid y
= 3.5. The borders on the left and right should only be showing half of
the tile. I might do the same for the top.
