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 :)

I'll change it, but this was also copied code from statusbar-view
```coffeescript
    # Let's go through all the violations reported
    for item, index in messages
      # Condition for cursor into error range
      showInRange = (item.range?.containsPoint(position)) and index <= 10 and limitOnErrorRange
      # Condition for cursor on error line
      showOnline = (item.range?.start.row + 1) is currentLine and not limitOnErrorRange
```
