Inline message view

Show lint messages inline, next to the code that it applies to. 

![atom-inline-messages](https://raw.githubusercontent.com/mdgriffith/atom-inline-messages/master/img/inline-comments.gif)

Theres a new setting to enable the inline messaging.  I did also mess with the default config to stop the statusbar viewer and activate the inline messenger.  

It looks to be running fine for me, but probably needs a bit more testing than that :)
