Added TrustedDomains() and SafeRedirect().
Sort by DateInserted instead of DateLastComment in the /categories/archives so that an index can be used in the query.
Use SafeRedirect() instead of Redirect() in the discussion controller.
Cache the category path instead of the category url so that the urls don't get messed up when the community is browsed from different domains.
Merge branch 'stage' of github.com:vanillaforums/Garden into stage
