Changes to level tiles

New tilesets and level layout.
Debugged my new level
Re-textured level without silly old platformer tiles.

The level is stable without those old platformer tiles. Adding a
background layer in Tiled still causes some player visibility issues, so
I removed the layer.
Renamed my level so I could merge with Mike's Dev Branch

Added Hero derived classes

I added 3 hero subclasses that override the LoadContent method so far. I
also changed the game icon and game thumbnail images. No more Indiana.
