Indicator in tag manager search whether tag is already present or not with different indicator for if present on all files, some and maybe none.

This could likely be satisfied by #994

I would think adding a character to the front of that list of tag search results could help:

• + for adding to the current image
• - for removing the tag
• ± for multiple images where it can either add or remove the tag. It would still open the dialog asking what to do.

So in that case the result box could be + test (5) - testicles (310)
