Fixed Mos Eisley Ground Textures and Lighting file

I've also removed the erroneous 'bouncing' lighting entry and the obnoxious light bloom from the cantina. Who enjoys bright lights in their face while they're getting hammered? Additionally, I've restored the original map boundaries from the console versions, so you can now walk on top of the buildings connecting bases 1 and 2 without running into any annoying invisible walls.

It would have been easier just to rebuild the map with Pandemic's ModTools, but certain maps can't be rebuilt properly because the assets Pandemic provided don't actually match what's in the game. If you rebuild Mos Eisley, for example, you'll notice that shadows near bases 2 and 5 are glitchy and broken. Hex-editing allowed me to avoid these problems.
