Use the locationmap to expose internal resources. Renamed to bring into line with our naming conventions. Added better sitemap match using regexp to deal with sub-directories too. Added samples for xdoc-v2.0 and xdoc-v1.3 collections of DTDs. Initial plugin, moving stuff out of forrest core. The java files for this plugin are still in core - need to move them into the plugin. The sitemap generators are very specific to the filesystem of the Forrest core DTDs. Need to aslo enable it for project DTDs. Some enhancements are listed at FOR-221 Add an example of a local project DTD.
