Restored A1/Infinity Shuttle

A replacement for about a third of the infinity textures, using the M1 and M2 counterparts. An interesting effect... try it out and see. (Suggested for Aleph One, but works fine with Infinity ,as well. Textures haven't changed in size.) It's proposed as an early step in the Texture Replacement Project - start with the most colorful and detailed textures in the Marathon series, and you should get a more pleasing final result.
