Added a new modopts.ini setting for [fingerservice]:

include_location (defaults to true)
New comments at the top documenting the modopts.ini settings available.
Include misc flags (M for msg waiting, P for do-not-disturb) in web user status
active-users.json was excluding node with the POFF (do not disturb) flag set,
thus making the do_not_disturb property kind of moot - fixed.
