This PR adds status to mentions in chat and makes those mentions receive live updates.
There are known unfinished part in this implementation: when posting a message, status on mentions on that message appears immediately, but only if a user used autocomplete when typing the message. If user copy and paste a message with mentions into chat composer, those mentions won't have user status on them.
PRs with fixes for both problems are following soon.
