Added a new HideAdvancements option (now enabled by default) which hides advancement announcements from all players who can't see the advancement earner (if that player is in vanish)
Tab-completions for PlotSquared's /visit command should no longer be blocked for vanished players. This will require updating PV on both spigot and bungee. Please tell me if this works reliably and if there are any other commands that tab-complete offline players.
