Filter previously matched scenes in autotagger

[DublServ]

We currently have the option to filter out unmatched scenes in the results of autotagger. It would be beneficial to also be able to filter out scenes that have been matched already. Would reduce scrolling through to check if any on the page are unmatched.

Just add a search filter where stashid is null. As soon as you tag a scene, it will be removed from the list.
