+Support of hierarchic menus & page structures: 
+1. on configuration scope an additional parameter {:page-model [:flat | :hierarchic]} - flat will be the default. Flat mode is backward compatible.
+2. on page scope we respect {:navbar? [true|false]} in flat & hierarchic mode also.
+3. params now contain hierarchic pages. Pages is replacing no longer supported navbar-pages / sidebar-pages. Hierarchic pages may contain a sequence of children `{:children ({:title "child-page", :layout "page.html", :content " <p>child</p>"}) }
