Rather large redesign in order to avoid config phase.

This is a very breaking change. The whole application is now defined in the ratpack.groovy file, including all modules. This meant having to push the adaption point between Netty and the Ratpack runtime much closer towards Netty. Ultimately though, it's cleaner and makes the core less opinionated.

Static file handling is currently broken, with relevant tests disabled.
