Changed .g-panel -> .zone

as .g-panel - which is a rather confusing name to remember. Zone is
much better
[Examiner]: Resolved issue w/ question tagging

The list of topics was not getting rendered because the target tab-pane
was not being included for non-admin Examiners. It is now, and so everything
works the same as for Admins
Available examiners include non-Admins also
Changed query order to remove run-time error
 Added two new issues
[preview]: Show a random version when previewing questions

Not only does this bring variety, it is also a useful check for
seeing that all versions have been rendered properly
[audit]: Report question's UID as that is what is sent in an audit mail
