Fixed issue with two broken links
Added some missing add_slashes(), get_post_escaped(), and strip_tags() for $_POST, $_GET and $_REQUEST-data. Also for $_SERVER['PHP_SELF'].
Added multi-lingual Admin tool description. Moved Admin tool language text from global language file to module language files. Added function get_variable_content to allow extraction of variable without including files.
Added keywords to new Admintools files
Moved the admin tools from 'Settings' to the new section 'Admin-Tools'.
