Subject: [PATCH] Updated backend for staticpage plugin: 1. Functionality
 remains mainly unchanged. Only preview display has been changed from
 subpage-based access to id-based access, because subpage can be ambigous. The
 new feature required changes to selected(). 2. A hook-in is provided the
 generate a overview of all static pages when not editing a static page. This
 makes the overview page more pleasent for users. The functionality of the
 header remains unchanged. Only a list of pages is generated below the header.
 The style of this list is taken from entry listing to create a consistent
 look and feel for users.
