HUD and User Input

Once refactoring is done and hopefully minimalize errors with Physics,
I'll help clean up the code and add a Score Table.

I spent a long time trying to do something special, but then I said
screw it. Then I tried seperating the rendering code in main.cpp into
other files like game.h and game.cpp. Gave me a lot of LNK2005 errors
about multiple definitions. Sorry if I slowed you down Francis. I'll be
working on 179 most of the day Wednesday.
