/**
 * cPanel Password Driver
 *
 * Driver that adds functionality to change the users cPanel password.
 * Originally written by Fulvio Venturelli <fulvio@venturelli.org>
 *
 * Completely rewritten using the cPanel API2 call Email::passwdpop
 * as opposed to the original coding against the UI, which is a fragile method that
 * makes the driver to always return a failure message for any language other than English
 * see http://trac.roundcube.net/ticket/1487015
 *
 * This driver has been tested with o2switch hosting and seems to work fine.
 *
 * @version 3.0
