  主题管理：
  删除：/topic/control?id=1&deleted=1
  反删除：/topic/control?id=1&deleted=0
  置顶 3 /topic/control?id=1&displayorder=3
  沉底 /topic/control?id=1&displayorder=-1
  恢复正常排序 /topic/control?id=1&displayorder=-1
  高亮 /topic/control?id=1&highlight=  //TODO
  精华 3 /topic/control?id=1&digest=3
  取消精华 /topic/control?id=1&digest=0
  锁定 /topic/control?id=1&locked=1
  打开 /topic/control?id=1&locked=0
  移动 /topic/control?id=1&category_id=1
  分类 /topic/control?id=1&type_id=1
  以上操作可以多重进行
  例如把1,2,3号id的主题进行精华3和置顶1
  /topic/control?id=1,2,3&digest=3&displayorder=1
