Add option for adding multiple tags/genres in Library Management Settings

[itsteddyyo]

It would be great to be able to add multiple tags/genres, etc in the Library Management Settings. It could be done via multiple Textboxes (maybe always 3 Textboxes as i doubt one will need more or always adding a new one when the one above is being filled out). An easier alternative that would not take so much time would be to just split the text in the Name-Textbox by semicolon or so like in this screenshot:

I know this can already be done by just using multiple items/rules but if you have many rules like i have it gets confusing fast to maintain your rules and add new ones. I think this would greatly reduce the number of needed rules and make the settings more clear. Thanks for your great extension and that you took the time looking at this 😄
