Rewrite our build as modular maven components

This refactoring splits the code up into different components, with their own per-component CLASSPATH. By moving all of our classes into isolated components we can better isolate the classpaths and try to avoid unexpected dependency problems. It also allows us to more clearly define which components are used by the GWT UI and thus must be compiled under GWT, and which components are run on the server and can therefore use more of the J2SE API.
