  添加到编辑比赛页的入口[CI SKIP]

  添加admin编辑比赛页面以及js[CI SKIP]
  修改提交样式
  调整顺序
  更新
  Revert "修改比赛单个题目列表的样式"

  对盘题系统针对新测试服务器进行调整,该分支将不会并入主分支[CI SKIP]
  correct the path of test case in judger
  原来的dockerimage里没有MySQL-python,所以又改了下[CI SKIP]
  漏了一个import[CI SKIP]
  这是为了能以root身份运行celery[CI SKIP]
  为了在qduoj.cf上运行做了改动，因为判题和web都在一台机器上，这个docker image是从digitalOcean上download下来的[CI SKIP]
