Allow mass edits of visibility tags

[ThePiachu]

I currently generated a sector only to realise all of the tags are invisible to my players. To fix this, I'd have to manually go to each planet, edit, uncheck the visibility options for all tags, and save. Rinse, repeat for every planet in every hex, which is a long and tedious process. It would be nice to be able to edit the visibility of tags across multiple planets at once, or have some option to just "show everything to the players".
