Populate author name field with pair names/usernames

[salarkhan]

As referenced in #44, we should replace "Pear" with the Github usernames ( or real names ) of each pair member.

I imagine this will involve us making an API call to Github, so we should prob look into getting that API key as well.

So, this is stupid.

We're gonna have to change to using usernames instead of emails, because usernames are what the API requires in order to get info. What sucks doubly about this is that some people have an empty email field in the response JSON -- which means git-pear will need to tell people to update their emails in their profile in order to give "credit" to the user.

we should try and talk in meat space as this sounds like a substantial overhaul of our functionality (also i really like not needing an API key)

at the very least we should make the API key an optional argument so that novice users don't need to understand it's use

[salarkhan]

so, we've finally gotten to this point. the final...ish boss.

as we spoke of in meatspace:

• use the first part of the email address. ( the part before the @ )
• optional API key to get usernames/fullnames

speaking of, i wonder what the final boss is...homebrew?!
