Switch out grunt for gulp?

[deiga]

I've used Gulp recently in my node projects and it feels a lot...better and easier to handle than grunt.

Would it be ok to switch out Grunt in favor of Gulp?

Absolutely, although I've found that gulp is not necessarily very good for certain things that grunt is fairly good at (like watching the filesystem for changes and running a test web server). But I can't remember if I'm actually using any of that in this project.

A PR to switch over to gulp would probably be accepted, the only thing is making sure that the karma tests can be run nicely. I put together a helper for running karma in https://github.com/angular/watchtower.js which isn't totally perfect, but it works well enough.

So definitely, send a PR, I'll probably take it.
