Carousel thumbnails are not responsive

Images for the carousel have a standard class wp-image-id, so WordPress adds responsive images to them. But thumbnails do not have this class, so large images are always loaded.

To fix this I have to edit the file coblocks/dist/coblocks-1.js and add a class wp-image-id for thumbnails.

I tested it on the 3.1.5 version, but I use version 3.0.4, since the lightbox does not work in this version, as indicated in previous topics.
