Closes #52.

Description:

So I spent a few of hours on this but it is proving ridiculously difficult to get the github usernames from the name+email combination because of rate limits on the github api and the asynchronicity of the whole thing. See https://api.github.com/rate_limit for rate limits. To retrieve the github username the following endpoint can be used: https://api.github.com/search/users?q=liamtbrand%40gmail.com%20in%3Aemail.

To close this issue what I have done is retrieve the username and thus the profile picture for anyone who has their email specified as the github no reply email. This was done similar to #123 for the same reasons @Buster-Darragh-Major provided in the description.

Fetching profiles for non-github emails could be done, however a new issue should probably be opened for retrieving the usernames. Otherwise I think it is sufficient to fetch the profile pictures for the github user emails only.

Testing:

Must be done manually.

Steps for manual testing:

1. Open VisualGit.
2. Open a repository with github and non github users. (VisualGit is good).
3. Verify that users with @noreply.github.com emails have their github profile picture shown.
4. Verify that users with other emails have the first letter of their name or email shown.
