Intercept links to known documentation

I wonder if it would be possible to intercept (either during scraping or when clicked) links to known documentation. For example, the Backbone documentation contains quite a few links to Underscore documentation pages. It would be nice if these would open within DevDocs, since both are available.

This would be an improvement for offline use, and would be a nice enhancement for online use too.

Start by tracing how links are handled during scraping and when clicked, then inspect the available Backbone and Underscore documentation entries. Done means links to known documentation open within DevDocs and continue to work for offline use as well as online use.
