Updated article on fine-grained authZ

I recently updated my article on fine-grained access control.

1. CustomClaimsAppPolicyService.xml schema did not properly close the Global element.
2. The following step was added upon import of the schema:
Copy CustomClaimsAppPolicyService.properties and CustomClaimsAppPolicyService_en.properties to Access Manager's local directory, for example, /opt/SUNWam/locale.

Thanks for all the great feedback. Hopefully i'll get the time to write part2 soon!
