Merge in EAM from viewer-release

Remove the derpy stuff lindens like to do
Wide strings aren't normal strings

Make it all a bit better~
Redid the Duration floater because it was kinda icky,
gave it more flexibility~<3
Display parcel ban and access durations as dates instead of text, sortable!
Reworked the rather icky lookin' Access panel control ordering
Enabled lowering parcel ban time without needing to find and remove first
