Subject: [PATCH] allow to use etemplate apps as sitemgr modules: - extend
 etemplate's sitemgr_module class and set the $etemplate_method class-var to a
 method/menuaction of the app - the app need to return etemplate::exec()
 (otherwise the content is empty)!!! - the app need to avoid redirects or
 links, as this would leave sitemgr!!!
