Add LoadState + TMXMap import.

TMX map (from the Tiled map editor) can now be imported directly. When a
map is loaded, so are all of it's tile sets. Application logic can
create jaws.TileMaps from each Tile Layer in a TMX map by calling the
layerAsTileMap() method.

To accommodate and compliment the TMX import functionality, the LoadState
has been added.  The LoadState loads TMX maps (using jaws.TMXMap) and
provides a loading screen to alert the user of progress.
