ISIS-1406 from Dan Haywood

ISIS-1404: AuthenticationSessionProvider is now a domain service; removed the AuthenticationSessionProviderAbstract and Aware interfaces.
In addition, FacetFactoryAbstract now implements ServiceInjectorAware, none of the subclass FacetFactorys do. The intention here is that we can just let FacetFactory reach into ServicesInjector to pull out the domain services, such as AuthenticationSessionProvider impl'n.
