Require email address for all support tickets

We are seeing little benefit of allowing users to not put in their email
address. This will mean that you must provide it for feedback, not just
problems with the site.

There could maybe be some more refactoring of the support templates as
this is now very similar to the report a problem page but this is a
quick fix so haven't gone too in depth.
