vertx-lang-clojure

The first release of vertx-lang-clojure
so fare we have completed following works:

1. Auto generate Clojure api by using codegen, thus users could use vert.x api in clj context
2. Register verticle factory services, thus users could deploy ***.clj verticle directly without manually register verticle factory first
3. Provide verticle service with clj file e.g. my_first_http_sample.clj and when the verticle deployed the start method will be automatically invoked, this would be the main feature of Vert.x
4. There are some tests to test the functions

;todo
5) Website clj part could be generated now, but we need a CodeTranslator and I think we need to add ClojureLang in io.vertx.codetrans.lang package, thus we could translate java -> clj code on the website
6) Clojuredoc, we could use Codox to generate nice looking website documentations
