%s instead of %d in actions_delete()

In the actions.inc file, the last function, actions_delete(), uses the %d modifier for a varchar column (aid), when it should be %s.

Thus,

function actions_delete($aid) {
  db_query("DELETE FROM {actions} WHERE aid = %d", $aid);
  module_invoke_all('actions_delete', $aid);
}

Becomes,

/**
 * Delete a single action from the database.
 *
 * @param $aid
 *   integer The ID of the action to delete.
 */
function actions_delete($aid) {
  db_query("DELETE FROM {actions} WHERE aid = '%s'", $aid);
  module_invoke_all('actions_delete', $aid);
}
