All places just av/group names were being used are now name ui

Since NameBoxes are clickable, remove redundant profile buttons.
Removes a ton of RLV logic, now centralized inside LLNameUI
Removes excess functions that went largely unused

May no longer show if parcel sale is pending under the owner field,
this is weird and it's hard to keep this behavior

Also includes the missing setValue and getValue so this compiles,
that should've been committed way earlier, oops

Also adds ability for name_box to have is_group attribute, too!
