option to see whos in instance, while in it.

While in sarn you can't tell who's there unless you leave and check. During events a lot of times you won't see the entire team load in. It will say "x has joined the red/blue team" but only 1-2 of the 3-6 members. So you can't properly strategize or approach. We should be able to see who's in either of these by hitting tab or typing / something. Would also make sense to show who joins and leaves sarn again too.
