Manage T5DE rooms from the client; the AP+ badge on avatar cards

Chat Rooms > Manage (the t5de-room-manage patch) lists the person's T5DE rooms
(room_management_info.php?t5de=1) and saves them from IMVU's room dialog (room_management.php: create
with t5de=1, edit and delete naming a hosted room) as hub calls: the room, its moderators by name, and a
picture from the person's IMVU gallery, uploaded to the hub. The hub's refusals show in the dialog
(hub.Error keeps their message).

Avatar cards get show_ap_plus again, which IMVU stopped sending, from the person's public IMVU profile
(is_ap_plus).
