Suggestion: Cleanup Tab

[RuiNtD]

What's your idea?

There should be a tab to help "clean up" the backup folder. Some suggestions for options in this tab could include:

1. Automatically merging Differential backups into Full backups.
2. Manually removing games from the backup folder, with filter options for games that aren't being backed up by Ludusavi anymore because they are either not installed, explicitly unchecked in the backup tab, or removed from Custom Games. This would be useful to prevent accidentally restoring old saves on a new PC, especially if they've been unchecked by the user because they're already backed up elsewhere (like Steam Cloud), but never removed from the folder.
3. Converting large Simple format saves to ZIP format on a per-game basis (assuming Ludusavi even supports this?).
