Fixes to minimize excess files, make paths work, etc

Requires Sarbian's DDS Loader, of course, for the DDS files, and the EVE folder (but NOT the BoulderCo folder) from the current dev Overhaul install.
I still get city day/night textures as going over the RAM limit of my card, so you might need to rescale some files, or tell people with measly 2GB graphics cards to do it on their end. :D
