Adding visibility options for Item Activities

[Cruallassar]

In particular, adding a visibility toggle for users that are attuned/unattuned or when an item is unidentified, so an unattuned player using an unidentified item doesn't see unavailable-unless-attuned or identification-required activities in their options, but I can see other possible visibility options being useful as well.

With regard to identification, could also toggle labeling unidentified activities as "Unidentified Activity" when the item is unidentified.
