pull-requests: overhaul of the UX by adding new sidebar

- sidebar aggregates comments, todos, observers, referenced tickets, and reviewers
- live components push now comments, reviewer presence, and todo live via channelstream
- sidebar is collapsable, and stored in user session
- simplified number of information on the pull request page
- fixed and cleanup of the outdated comments and at version comments that in some cases reported wrong version assignment.
