 * Elgg 1.9.0-dev upgrade 2014050600
 * replies_to_entities
 *
 * Registers discussion reply subtype and adds \ElggUpgrade for ajax upgrade.
 *
 * We do not migrate discussion replies in this upgrade. See the upgrade action
 * in actions/admin/upgrades/upgrade_discussion_replies.php for that.
 *
 * This upgrade must be run even if the groups plugin is disabled because the
 * script will be removed in Elgg 1.10 and we don't want anyone to get stuck
 * with old annotation replies just because the groups plugin was not enabled
 * when site was upgraded from 1.8.
