[CGMZ] Autosave Enhancement - Version Beta R3

Hi all, today this plugin was updated to version BetaR3!
This update adds the option to save over the current file when autosaving instead of saving over the separate autosave file.
Some control over this was added for edge cases, such as starting a new game when all save files are taken up. Previously, this would assign the oldest save as the current save file id and cause autosave to overwrite this. A setting was added to prevent that.
You can also set any file id as the autosave file id if not using the option to overwrite the current file.
Note: If updating to this version from a previous version, please back up your save files before playtest to ensure you do not lose any save data. There were settings added that can allow this plugin to autosave over existing save files if configured in a certain way.
- Added option to save over the current file when autosaving
- Added option to prevent overwriting old saves with new games
- Added option to change autosave file id
