IRepositoriesClient.Commits -> IRepositoriesClient.Commit

[shiftkey]

This is a pluralized interface that we shouldn't really have:

https://developer.github.com/v3/repos/commits/

var commit = await github.Repository.Commits.Get("octokit", "octokit.net", "master");

We should mark this property as obsolete and introduce a new property which is singular:

var commit = await github.Repository.Commit.Get("octokit", "octokit.net", "master");
