Create repository screen filter

Hey everyone, reading the issue #286 I was wondering that maybe we could create a filter feature for repository field.

I was thinking about 2 options.

1 - Add tabs ( Similar that one has in search tab) containing `All, Public, Private and Forks`.

2 - Add a filter button in the header bar in order to open a modal with many options as order by date and alphabetical. And some checkboxes to filter `All, Public, Private and Forks` types.

What do you think about? 😄

首先阅读 issue #286，并定位应用中的 repository 字段和现有搜索选项卡。确定接受哪种提出的筛选方案，然后将完成标准定义为能够将仓库筛选为 All、Public、Private 或 Forks，并在包含此功能时按日期或名称排序。
