Replace Grunt with gulp

[demisx]

Replace Grunt builder with gulp.js. Tried to preserve the name of the tasks as much as I could, so they simply map from grunt <taskName> to gulp <taskName>. Please review.

Fixes #10.

is this necessary?

Their protractor config doc says set it to null if you want to let selenium server find its own port. I see it works without it too by defaulting to 4444, but not sure if it's gonna pick another port if 4444 is taken. This is what I use in all my configs. I can remove it here, if you'd like.

Nope it's fine, makes sense to leave it in even if it's the default just to be sure. In the past I haven't had an issue either way.

Can you change the tabspacing to 4 spaces per tab (soft tabs) in the Gulpfile?

and also follow the convention like this:

var x = function () {

notice the spacing between function and () and () and {

[demisx]

I can't seem to reply under your last comment anymore, but I've fixed the function calls to insert that extra space before (). I mostly code in CoffeeScript, so got used to their standards.

I've also replaced 2 space indentation with 4 (cried while I doing it, though :) )

Thanks @demisx I know a lot of people like the 2 spaces, I like the readability of 4 spaces and I'm used to it from my previous experience. Everything else looks very good though! Thanks so much for pushing this through :)
