/**
* Tries to render a delegate action's default template if it exists.
*
* Because we can't always know the short name of a delegate (like we can
* with a controller), the default view spec of :controller/:action:suffix
* won't work for us. This means we can't just prepend our default paths to
* the view script paths. Instead, this function changes the viewRenderer
* spec to just :action:suffix, puts in the default dirs, tries to render
* and then flips back the settings afterwards.
*
* @todo Ugly, needs refactoring
* @param Zend_Controller_Action_Helper_ViewRenderer $viewRenderer
* @param Zend_View_Abstract $view
* @param string $action Name of the action, without the "Action" suffix
