Bug fix and minor improvements

Improvements:
- Add instant feedback upon setting a different
  presence for account (local echo)
- Sort room members by power level and then
  presence
- Periodically update members' `last_acitve_at`
  field on the room pane
- Move status message field up on account context
  menu, and put invisible before offline again

Bug fix:
- Do not try to override presence set from
  another client, accept it
