[request] Necessary Save renaming mod

[Mugentsuki]

Anybody who runs multiple characters need this mod, one to rename autosaves to say autosave. Putting a manual save over an autosave (accidentally) will cause it to be automatically overwritten, which can lead to a lvl 30+ character disappearing eternally to never see the light of day again. (Yes, I speak from experience, all because I wanted to try out a more VATS based build.)
