Added a title screen, and remade the gameover screen.

 Its still technically a WIP title, but whatever.

Cleaned up some of the back-end (w/states)

-A few map fixes here and there.

-cleaned up the title screen
-removed the 'menu' as it was redundant. Everything was in the hud anyway. Could re-implement it for a map or something. But that's not a priority.

-considering adding a wall switch that toggles. something to make the dungeons interesting. Will have to replace a few sprites though.
-still need to make the enemies move. I'm probably going to ask for help on that.
