megaglest: new package

MegaGlest, 3D real-time strategy game
I thought so too, but `ldd` on output binary revealed that bunch of libraries where not found, and of course running that binary exited with missing libraries error... even patchelf did not help.. when running `ldd` pachelf-ed binary said that versions of required libraries did not match. I guess that is a bug in the build scripts of the game. But the game itself works flawlessly with this.. fix.
