spock-tapestry: added support for @InjectService, @javax.inject.Inject

[tawus]

Added support for the preferred way of injection using @javax.inject.Inject. Also added support for @InjectService.

Thanks for the pull request! Looks good. Would you mind to update your code to avoid static references to @javax.inject.Inject so that we stay compatible with JDK 5? You could use org.spockframework.util.ReflectionUtil.isAnnotationPresent for production code, and org.spockframework.EmbeddedSpecification for test code.

Thanks Peter for accepting the request. I have removed the references to javax.inject.Inject.

BTW EmbeddedSpecRunner is very cool!
