Bugfixed the Elfloader; resolves a bootup crash in Psychonauts. 

Renamed MemoryAlloc to SafeArray, and added linux files to the Win32 solutions (they're disabled, so they don't compile or anything -- I just needed them in the solution so that I can more easily update Linux code when I make API changes to the GUI)
