Vertx update

Updates vert.x to 2.0 and streamlines the JSON creation to match that of the Netty handler. 

This also just launches vertx from the setup.py via invoking the vertx CLI directly on the java source file (which you can do in 2.0) thus removing the need for the compilation step.

Still debugging some python installation issues locally, but the vert.x stuff all compiles and launches via vertx CLI.
