Overhauled and simplified Web Script integration. #49
Integration is now limited to org.springframework.extensions.webscripts.UriIndex.
Limitation: the standard Registry implementation caches URI lookups, also for URIs that do not map to any Web Script yet.
Workaround: when in doubt, reset the Web Script index to ensure URI mappings are up-to-date.
Removed obsolete classes.
Minor changes to Control Panel
