Starting from Adriano Bonat's contribution via GitHub (http://github.com/tanob/jbehave-core), add a jbehave-groovy module with extensions of core for Groovy-specific support, similarly to IOC framework extensions (Guice, Pico, Spring).

Initially, it will contain a GroovyStepsFactory to create steps instances from Groovy scripts.

It should also provide support for @UsingGroovy annotation, to specify the GroovyClassLoader and the GroovyResourceFinder.
