MainForm.ClearSaveRam() no longer deletes a disk file.

From my reading of the code, this should not affect movie playback; the saveram from disk is not used when starting playback or recording of a clean movie.
If for some reason I'm wrong though, that problem should be addressed directly instead of deleting the file.
