* dev:
  增加了比赛列表页
  [后端]去掉了用于生产序号的javascript,改为使用模板过滤器实现(我的所有提交)
  [前端]修改完善了添加比赛页面,  比赛列表功能仍不全面,稍后改进[CI SKIP]
  修改了css引用方式[CI SKIP]
  [后端]修改了contest中 api-docs 的小bug[CI SKIP]
  创建前台比赛列表
  去掉冗余语句,因为page变量已经有默认值了,不能为空
  [后端]前台我的提交页面 增强提交序号的显示,原来是显示真实id即随机的散列值,不好看,现在改成自然数序列,但需要结合javascript生成,且是相对值,因为数据库里没有这个字段,有点别扭了.   第二,添加了用户没有提交记录的反馈.   第三,本打算增加筛选功能,但因为URL难以统一作罢,只有在增加新的url才能较好的处理,下次再说拜
  [前端]比赛列表页面(后台)的进一步完善,不包含api
  [后端]修改了我的提交列表的模板样式,整理格式
  [后端]修改我的提交页面,去掉了冗余语句,并添加测试
  [后端-前台]添加了submissions分页显示(只显示当前用户的提交),调用已有的view完成单个submission的显示.显示界面与问题分页显示统一.问题是id的显示.url:http://127.0.0.1:8000/my_submissions/
  [前端]修改添加比赛页面,新增了使用小组api查询该用户所创建的所有的小组的功能[CI SKIP]
