Mark ban text as html safe
Update commonlib to get https://github.com/mysociety/commonlib/commit/735dbe574c63650e5d086eea9f7ad57bbd76927f, which should allow non-ascii config variable values.
Merge branch 'hotfix/0.9.0.1'
Bugfix for the case where a suspended user sends a contact message. Their name (with the '(account suspended)' suffix) is marked by the translation call as HTML safe, so escapes the angled brackets when they are appended to it in the contact mailer code. Use string interpolation instead.
