Gulp

Added delete functionality so that the gulpjs version can send delete requests. I added all the delete functionality from  the original gruntjs version the same way, the only thing I had to change to get it to work properly in this version was in client/src/views/contact_details.js was the remove() and destroy() logic.

	this.model.destroy({
	  success: function(model, response)  {
	      window.App.data.contacts.remove(this.model);
	  }
	});
