Don't display categories for deleted bodies

When a body has been marked as deleted (currently only exposed in the
Zurich cobrand's admin) the categories for that body should not be
available on the report_new form.

Prior to this change there was an error running the
'zurich-overdue-alert' script, because it wasn't expecting the
'bodies_str' field to have any entries in the format 'x|y,z', this
prevents this problem from happening in the future (though it doesn't
fix any existing entries with this issue).
Add body deletion to admin interface.
Include version number on admin config page.
Version 1.3.
Simplify .content width/margins.

Reduce magic numbers by switching fixed width to a margin elsewhere.
This has the added bonus of making the 'middle-width' .content
have a pleasing right margin.
Tidy up use of main width a bit.
Merge remote-tracking branch 'upstream/master'
Remove cached photos if hidden in admin interface.

Use the internal hash URL of the photo so that it can still be seen in
the admin interface.
Copy of main privacy file to work on.
