Yes you read that right. It's back! Oh god it's back
Instead of modifying the db, an external json file is made holding the custom info for your library (meaning it's even easier to remove should I so choose)
Reworking to just override the variable and use said var instead of having the current/original logic that existed before
Custom covers are now saved in a new folder, likewise to upstream
Also like upstream, custom covers can be added to manga without covers (closes#49)
(I'm so sorry Carlos)
