Give every user their own bot face

A bot's face and status line live in bot_user_faces, one row per bot and
user, set by jobs for the user whose conversation they're in. Needs-you
and working only show to that user; every bot read overlays the viewer's
face (botFaceSql) and pushes go to the user a face change is for.
