Support optional typing for interfaces and constants

• Add Angular style InjectionToken class as a variant of InjectableId to support implicit typing of constants and interfaces.
• Minor update to Binder.resolveSingletons to make it chainable (aka return the Container/Binder instance).
• Minor updates to ReadMe.

Support resource cleanup for Singletons

For Singleton type services, the @Release decorator allows for notification to a service when it is no longer needed (e.g. service.destroy()).

The Container.releaseSingletons method can be used to release all Singletons in a Container. This might be done for instance when you have allocated a child Container for the duration of a single transaction and want to quickly unsubscribe and release resources allocated during that transaction, before also dropping your reference to the child Container itself.

Update devDependencies.
