This module exists solely to package all other gwt modules into a single
uber jar. This makes deploying to non-mavenized targets much easier.
Of course, you would be wise to inherit your dependencies individually;
the uber jar is intended for projects like collide,
which have complex configuration, and adding many jars would be a pain.
The newest version!
