Tree of Savior Forum

Add a link to staff posts stream to the list controls bar

As the title implies I suggest to make it easier to access and overview latest staff posts by allowing to visit https://forum.treeofsavior.com/groups/staff via the control bar ( latest, new , unread, top, etc)

You should also add a link to https://forum.treeofsavior.com/groups/staff/members to the user menu where you find link to various categories.
