Move the info into gutter

[surdu]

It would be nice for the jshint messages to be displayed on hover for the line number in the gutter rather than displayed bellow the code, out of context.

If this is wanted from this extension, I could implement that myself and create a pull request.

PS: love to see the package is written in JS and not Coffe:shit: :+1:

Go for it @surdu - I was thinking something similar myself :)
