Title: Remove 'buttons' HTML attribute from submit and reset buttons

The 'buttons' class variable was causing a 'buttons' HTML attribute to
be generated (buttons="danger info primary success warning inverse link").

The leading underscore is parsed by Zend_Form_Element::getAttribs in order
to remove it from the HTML attributes list.
