🔑 Optionally save acquired keys into DB

[Cocodrulo]

Describe Pull request This PR makes so the aquired keys will be saved into DB so when the server restarts you will still have the keys you were given. This feature is optional and can be set in the Config file. The PR is made to answer this suggestion [SUGGESTION] Database keys. I believe that is easier to make this into player metadata instead of a full new database table.

Hopefully this gets in. It's kinda annoying.
