Merge branch 'develop'
Configuration update
Added urlFactory to HttpRequestAction

There is two ways of passing url parameters to '''HttpRequestAction'''. First one is to pass it as a string:

	new HttpRequestAction({url: 'some/url'});

Or you can pass a function:

	// Following example use eventObject.url passed to an instance of Action to construct a url
	new HttpRequestAction({url: function (topic, eventObject) {
		return eventObject.url;
	});
Added specs for urlfactory
