AddRules(): multi-call to setting filter rules.

If prefixed with a ":" (colon), a filter rule will be added.  If not
prefixed, a static replacement will be added.

ex:
array(
':controller' => array('CamelCaseToUnderscore','StringToLower'),
':action'     => array('CamelCaseToUnderscore','StringToLower'),
'suffix'      => 'phtml'
);
