Gwt evolution

Hi,

I have moved GWT compilation to the war (the gwt-maven-plugin suggests this for more productivity).
Migrated to GXT 3.1.1, GWT 2.6.1 and Jersey 2.12.
Implemented the automatic registration of Spring beans in Jersey (with a small workaround for GWTAuthenticationServiceFacadeImpl which I expect you to provide a better solution).
I have also tried the SuperDevMode, but found it to be slower than the regular one.

Regards,
       Constantino
