[#108]: Part solution to the problem of auditing questions ...

Added ability for examiners to audit each other questions.

Questions come up for auditing when they are tagged. At that time,
the question is sent to an examiner other than the original author
for a first look.

Unless some gating issues are found, the question is kept in circulation.
Disable the just audited question in #pane-audit-review

Corrected logic for adding 'fav' class to a just favourited question
[qzb-filters]: Re-implemented how filters work during quiz building ...

The new scheme relies on class attributes being set on .single-lines
and a [filter] attribute set somewhere up the hierarchy

Currently there are 3 filters - for favourites, selected and show-all.

KPNS: Basis for showing selected questions is wrong
[qzb-filter]: Removed old code
