new users now have a prompt to set their campus, on the groups join page #c4cPulse

When someone goes on the pulse for the first time, on the join a groups page, there is now a message telling that they they need to choose their campus first. That link brings them directly to their profile edit page (they won't need to click "Edit" -- it will automatically be in edit mode) and will make the "Campus:" prompt be red to get their attention. Once they save, there is a notification that they can now join a group, with a link to the join groups page. The intent is to make it easier and clearer for a new user what needs to be done to join a group.
