Relaxed the requirement that an acs object type's specified table nameactually exists (or is null), due to broken packages like categories.I even provided an upgrade script and bumped the package version number.
Removing wrongly named upgrade script. Otherwise it appears at the top of the list for scripts to be ran when upgrading. Content is included on upgrade script upgrade-5.7.0d10-5.7.0d11.sql anyway.
Adding parameter show_page_references in order to control weather or not to show my-references includelet at the bottom of the pages. Bumping up version number.
