Refactor CLI argument parsing

[gasi]

I originally built this to support --ignore path1,path2 CLI option for #99, but then realized CLI options didn’t get passed to wrap.js, so I made the change without this. Nonetheless, this uses one of the most popular CLI argument parsers which will enable easier adding of new options in the future.

Enjoy!

Awesome, I wanted to to do something similar since ages! I've added you as collaborator as well as module owner on npm. I currently don't have the time to cut a new release, so it would be rad if you cut do it.

@fgnass Thank you for the quick reply on this, accepting my changes, and making me a collaborator — With great power comes great responsibility. 😄 I will cut a new release and push to npm 👍

@fgnass I added some tests, cut 2.7.0, and published it to npm: https://github.com/fgnass/node-dev/releases/tag/2.7.0 😃

@gasi thank you so much! Ignoring files was one of the most requested features from the beginning of this project. I didn't like the idea in the first place because it somehow violates node-dev's zero-conf philosophy but I don't see any better solution for universal/isomorphic apps. I'm really glad you jumped in to help me maintain this project. Thanks again for your awesome work.

Woot @gasi!
