API to show details of a specific sha1

We should have an API which returns the details of a specific commit. This should include the list of files, diff of the commit (whole), diff of every file.

User should be able to select a commit from any "history" or "log" (like ahead or behind) and then, able to (get) the commit details from API and show it in the Browser.

One way to do this is to check if Gitlab offers an API for this purpose?

Update: Jan 17

1. Improve the UI and show a good format for Git History. Instead of vomit JSON, rather show something useful like `git show <sha-1> --name-only`
2. Show a button on the UI - which says - "SHOW DIFF" -> shows the diff for that sha1
