Blame doesnt update real time when editing with gutter open

[alexcorre]

Steps to reproduce:

• open a file
• toggle blame gutter to show it
• edit the file while blame gutter open
• blame doesnt update and is therefore innacurate

Closing this as of #31 when you save the file, blame is updated. thanks @dmnd

I think this is still worth keeping open since updating in real time would be better what what I implemented in #31. But maybe #3 would cover it too.

[alexcorre]

youre right. #3 is close but the two can be fixed independently. Will leave this one open. As far as #3 i started looking deeper into today and know what needs to be done. Itll take some change, but i'll submit a PR once its ready to get your feedback on the React stuff needed.

Also want to make sure that editing outside the editor doesn't get overlooked. (e.g. checking out another version of the file while the file is open and git blame is visible in atom)

[dmnd]

@bblack can you open a separate issue for that? I think it's probably an easy fix given it already updates on save. It's probably just a matter of listening to the correct event.
