Many IDEs show "You (x minutes ago): Blah blah blah" or similar in code, even if you don't ask for this. It's great, because not many people are aware of git blame.

Adding this to Porcupine means that there will be 3 ways to do the same thing:

• Run git blame
• Press b in GitHub when looking at the file
• Look at the line in an editor

But I think it makes sense, each of these ways has their advantages and disadvantages.
