* Modifies registration form.

* If currently loaded form is registration form then this function does few things:
* - removes Username field (field with name "user_login")
* - moves password fields to the end of the form
* - validates user_email field as a usersname (and email) to make sure this email
* is not already being used as a username
*
* @since 1.0
* @param Daq_Form_ObjectAbstract $form
* @return Daq_Form_ObjectAbstract
