Added teleporter class, added its sprites to the TowerGame class for
initial loading, and commented in tile that we dont need a new class for
pressure plates, they can simply be different styles of tiles.

Teleporter currently works for first level.  Need to find a way to
create a teleporter list as the level loads for each level.  May end up
just hard-coding one in for each level.  Also need a way for the player
entity to access this list for use in its update method.
Teleporter infrastructure added, new level all about teleporters added! 
Only one real teleporter per platform, the rest send you to beginning.
Added Toggle Tiles (FadeIn/FadeOut)
