[Bug 836321] Parse about:support data if possible.

[Bug 841851] Don't disable troubleshooting info.

user, because maybe they will want to remove data from it.
[Bug 683639] Hide archived documents in AAQ.

[Bug 844933] Only accept troubleshooting dicts.

There is apparently some questions in SUMO that have this data as a list

Being specific about the type will prevent this kind of error.
[Bug 843766] django.conf.urls.defaults is deprecated.

[bug 845165] Allow email changes if you're not logged in

The template errored out if you weren't logged in, but when you're

the email with the link, then click on the link--there's no guarantee
that the user is logged in.

This nixes the crumbs if the user is not logged in thus alleviating
the error.
