Kevin Roast 577d45c551 More fall out from Template/Script refactoring:
- fix to missing annotated service method (caused script command servlet to fail)
 - spelling mistakes in annotated service method parameters
 - cleanup in AbstractWebScript

Added ValueConverter concept to Template API - similar to JavaScript API ValueConverter, for a consistent mechanism to recursively convert Alfresco node properties to template accessable objects.
