Simplify syntax for injecting into an interceptor

_From [eric.jain](https://code.google.com/u/102186567666012743407/) on January 29, 2010 15:07:43_

Instead of e.g.:

  Timer timer = new Timer();
  requestInjection(timer); // injects e.g. a Logger
  bindInterceptor(Matchers.any(), Matchers.annotatedWith(Timed.class), timer);

...it would be nice to simply write:

  bindInterceptor(Matchers.any(), Matchers.annotatedWith(Timed.class),
Timer.class);
