Add DM custom images, DM statuses, Member Tile statuses

[nushea]

Description

Adds DM custom images and topics because i loved them when i was using fluffy, present under a new setting that is on by default, so that within DM navigation one can have any image as the DM's icon, helping me personally at least with secrecy when screensharing.

(example where in the background it is visible that it is a dm with someone but it has a custom image)

(example with some spaces that have custom images, one having an intentionally ZWS description)

(example of dms with statuses, offline being marked as not showing a badge)

(example of the new look of the member drawer)
