Add power level to the user details dialog

The only way to check a user's power level is to haul yourself over to
the member list, which is cumbersome but also hard to parse - especially
if a room has lots of members.

This adds the user's power level to the existing details dialog. For
example, this makes it easier to identify someone as a moderator if they
sent a message in the room.
