MEL Script: Incremental Save

This mel script will automatically increment your saved scene for you. Simple and sweet, just source the script to either increment your already numbered scene or to add a serial number at the end of a filename without one. Also adds your new file to your Recent Files list in the File menu. I recommend saving it and then calling it with a shelf button for easy access.
