Also, don't fetch vCards in rosterHandler. This could be very expensive for
large rosters, instead we'll fetch them when a user comes online.

Additionally:
It's not feasible to get the current user's fullname from a vCard all the time,
so we still get it from the DOM for now.

Also set bare_jid, domain and muc_domain on the xmppchat obj and not the
connection obj.

This was the last thing still using burry.js, so we now have one less
dependency :)

- Use a template to show the day's date.
- Use time element for the date and datetime attr

Roster changes are listened to on the rosterview and the applicable chatbox is
updated.

Custom status messages are now remembered upon page load.
