Add support for Gulp

I've been working recently on awesome project and I was tried of waiting until my code gets compiled and browser refreshed. It is not perfect, on my old macbook pro I have to wait like twice longer than when editing in Chrome console but I understand that compiling coffee or stylus and page refresh might take a while, about blink of an eye.

What it do?
- most of the stuff that grunt but FASTER and in awesome way ; )
- sass / stylus with nib
- first question asks if you want to choice experimental Gulp instead of Grunt so there will be no harm for Grunt lovers

What it can't do yet?
- compass
