We don't push our code to a Maven repository, so there only reason
to construct source archives is to feed source files into the GWT
compiler. Move the source plugin onto only the packages that we
feed into the GWT code, allowing the others to skip this step.
This fixes a "bug" in a later change that adds the Prolog Cafe
translater to the build process. Without this change first, the
Prolog Cafe translator is firing twice for every Prolog source file
that is part of our standard build.
