interoperate between primitive and boxed values in injector

[realityforge]

As of v0.05 if a component requests a value of type int and a value of type java.lang.Integer then they are considered different service requests. We could refactor the internals of Sting to treat them identically. This would make it possible to provide a configuration value (i.e. @Named("server.port") int getPort() { return 8080; }) that could be consumed optionally (i.e. @Named("server.port") @Nullable Integer serverPort) or added to a collection etc.

This should not be hard to implement but would require a lot more tests.
