Fix release artifacts so cucumber-clojure can be released.

/cc @nilswloka @rplevy-draker @hiredman

Release 1.0.0.RC23 does not include cucumber-clojure because sonatype-nexus (where jars are deployed) refuse to release artifacts that don't have javadoc (idiotic, but that's the way it is - see #231).

The workaround is to include a dummy java class (or perhaps a package.html) in cucumber-clojure now that the entire backend is implemented in clojure.

At the same time, we should also exclude the various examples from the release.

I don't know how to fix the javadoc issue, but would like to comment on the examples:

An updated clojure example is available at https://github.com/nilswloka/cucumber-jvm/tree/new-clojure-example. I will send an pull request for that one once I've released a stable version of the lein-cucumber plugin used in the new example (probably not before lein 2 and cucumber-jvm are stable).

Awesome! Bring it on. I'll handle the javadoc issue.

Ran into this one again for #1336. Fixed it using:
