 * Defines the display mode to use for the results of a SQL query
 *
 * It uses a synthetic string that contains all the required informations.
 * In this string:
 *   - the first two characters stand for the action to do while
 *     clicking on the "edit" link (e.g. 'ur' for update a row, 'nn' for no
 *     edit link...);
 *   - the next two characters stand for the action to do while
 *     clicking on the "delete" link (e.g. 'kp' for kill a process, 'nn' for
 *     no delete link...);
 *   - the next characters are boolean values (1/0) and respectively stand
 *     for sorting links, navigation bar, "insert a new row" link, the
 *     bookmark feature, the expand/collapse text/blob fields button and
 *     the "display printable view" option.
 *     Of course '0'/'1' means the feature won't/will be enabled.
 *
 * @param   string   the synthetic value for display_mode (see a few
 *                   lines above for explanations)

 *                   without any programmatically appended "LIMIT" clause

 *                   elements
