Added a second map and 40ish more tiles

I added a second map file and about 40 more tile stats have been
defined. Making this one map took longer than expected because I was
loading in more tile definitions, so I will make two more 2mrow
hopefully. For now, I have to do other hw.
Other Changes:
- GameEngine.cpp:
- changed the render clear color to white because some of the tiles have
"white" sections that are actually clear and must therefore be drawn
over a white background
- Changed the drawn map to TileMapTR.cpp
NOTE: Just so you guys know, here are what the initials in the tile
definitions stand for: T=top, M=mid, B=bot, E=end, L/R=Left/Right
- Map.cpp; tile defs
- Tile.cpp: pre-processor defines for tiles
