Integrates Pull Request #20: Fix for #16 - Provide an OSGi friendly security framework

A refactoring was done to integrate this change. The refactoring consists of:

- Renaming of AuthorizationHandler and AuthenticationHandler formerly ...Sevice
- The two bundles were merged together to keep the API minimal. If some user wants to provide a
different implementation we can make the SecurityAdmin public.
- Bug fix to allow null Principals
- Adding unit tests for the provider
