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. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@5535 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
