So, anyway... graphics

It's not finished yet.  Made some 20x20 pixel images.  Now getting them drawn onto the screen based on map generation.

1. Just need to fix up all the other links to the different terrain types.  
2. Relink location to image displayed.
3. Add Fog back to map
4. Alpha levels based on exploration level
5. other stuff...

~10 mins later *edit* 
Sweet!  Now it looks like I need to tweak the map generator to get some more 'realistic'  (aesthetically pleasing) tile arrangements, and I think there is too much sand (which used to be water in the previous iteration).
