show all sub-statuses of a project 

## Task

* Currently when click on a project (https://sitture.github.io/commit-status), it shows the commit history of the project. But we'd like to change that so that clicking on the project shows git commit status of each tasks in the project and each status links to details in a new tab/window.

E.g.

Project A
- Sub Status 1
- Sub Status 2
