Display a user's institution when inviting him to join a group

[Kristina Hoeppner]

When a group admin is at http://URL/group/inviteusers.php?id=163 (currently request or invite membership groups) and searches for names, it is difficult to see who is who if there are two users with the same name / display name. One way of improving this for large sites that work with institutions is to display the institution name alongside.
