ESLint, Cleanup

[bkendall]

Though this looks like a large change, the quick summary is that it's a lot of cleanup, and not a lot of functional changes:

• Use eslint instead of jshint. New config is in place, and npm run lint is correct
• Removed lodash! Functionality has been replaced by https://github.com/tjmehta/101 functions
• Added testing for iojs. Since it's around, we may as well support it... though I think it will only be on 'best effort' from our side...
• Cleaned up the README a little as well

@tjmehta I think I used the appropriate 101 things in replacing lodash. Could you take a quick once-over and make sure I did? The big one I had to change out was being able to just iterate over all the key-value pairs in an object (just went with Object.keys(...).map(...), since there's nothing I can think of that will easily do that in 101 - maybe an idea?).

strange that we are calling newPort() here. But I can see that it works
