Error E-mail Fix

Previously the error e-mail skipped the first \Exception object in the chain when displaying exception information.

This assumed, however, that the only errors the error e-mails were reporting were errors that were thrown as exceptions not of type \CivicInfoBC\HTTPStatus, and were therefore automatically wrapped in a \CivicInfoBC\HTTPStatus object by the \CivicInfoBC\ErrorPage class.  This is not the case.

Accordingly the error_email.phtml template has been updated to display all exceptions in the chain.
