Refactor AddImageTitle rewriter.

* Only processes images with `src` **and** `title` attributes (others are ignored).
* Processes **all** images in the document (not just the first one).
* Wraps the image and its title attribute in a `figure` tag with the title attribute's contents in a `figcaption` tag.

Updated xkcd rewriter unit test.

Added another xkcd rewriter unit test to check rendering of images without title tags.
