Update _actions.inc.php

Added a QAction called QRedirectAction. It allows you to redirect to a page without the need for a server or ajax request.
$btnControl->AddAction(new QClickEvent(), new QRedirectAction(''http://google.com"))
is the same as
$btnControl->AddAction(new QClickEvent(), new QJavaScriptAction(''document.location.href='http://google.com';"))
