Subject: [PATCH] Add action to user detail dialog to search for their messages
 in room

In other messaging applications (e.g. Discord) this is possible through
text modifiers like "from:@user". We don't support that, and I'm not
super keen on implementing yet-another-parsing-thing, so an action in
the user detail dialog should work for now.

Very useful to sift through large rooms but when you only care about a
specific person's messages (maybe your own?)
