This builds on work by @anjackson . I'm submitting it for discussion. It requires more testing before considering merging.
I've modified the two extractors he wrote, eliminating the BL specific, recrawl, elements. I renamed them to match Heritrix extractor naming conventions. I also added a new hop type, M (Manifest) for the links extracted by them. Other than that, they are mostly as Andy wrote them, barring a few minor tweaks.
As the sitemap extractor requires a new dependency (crawler-commons), I added that to the 'modules' sub-project. This creates a dependency conflict as crawler-commons requires a newer version of commons-io. I upgraded the commons-io (from 1.4 to 2.4) in the 'commons' sub-project. As far as I can tell this doesn't cause any regression.
