Add support for srcset attribute URLs in img tag

[anvaynk]

Need to include the feature to match the list of urls contained in srcset attribute of an image tag!!

Doesn't it work if you add it in your config?

[anvaynk]

The thing is that if we add multiple urls with different device pixel ratios(DPR), it encodes the DPR alongwith the urls, this should not happen.

That is a different issue and you should provide a test case for that.

@XhmikosR Unfortunately srcset doesn't work properly. Consider this example for html: <img src="image.jpg" alt="image" srcset=" image-1024_2x.jpg 1024w, image-1224.jpg 1224w, image-1400.jpg 1340w, image-2800_2x.jpg 1340w, image-480.jpg 480w, image-768.jpg 768w, image.jpg 1340w ">

After running grunt task it became: <img src="//some.b-cdn.net/image.jpg" alt="image" srcset="//some.b-cdn.net/image-1024_2x.jpg%201024w,%20image-1224.jpg%201224w,%20image-1400.jpg%201340w,%20image-2800_2x.jpg%201340w,%20image-480.jpg%20480w,%20image-768.jpg%20768w,%20image.jpg%201340w">

in the gruntfile I've added inside options.html this line: 'img[srcset]': 'srcset',

The issue here is that there is a simple string rewrite and srcset should be treat as an array.

PR's welcome as usual.
