Changed MisoSceneModel so that it knows about the view width and height.

It no longer stores base tiles that are not visable in the view,
in fact it stores the base tiles in an array almost half the size as the
fully expanded scene array, and this new smaller array is used everywhere:
when saving the scene, serializing it to the user, or saving it in
the database.
We must now use the getBaseTile() and setBaseTile() methods to access the
base tiles because they are stored in this compressed format.
Also removed the fringe layer completely from the MisoSceneModel.
