updated main to actually show the current pos.
Added some simple map data (see map.h). Added some simple
testing of it to main.c. Program now generates walls randomly.

The viewport is now fixed on the player, who is in the center
(had to make VIEWWIDTH and VIEWHEIGHT odd to make it directly
in the center).

Also, added primitive collision checking for map. You can only
move into a spot with a floor, currently.
