[Feature] Exclude (= ignore) studios and performers

[IAmKontrast]

Although I like the option to add performers and studios to your favorite list, I miss the function to ignore / exclude these too.
Besides the heart (Add Favorite) there could be another icon which adds the object to the excluding list. All items on these lists are no longer visible on stashdb for the user.
User profile should be extended with favorite/excluded lists to remove added items again.
Filter for favorite studios/performers should be updated to this new function. Excluded should be treated as opt-out.
