Remaining poms updated to 2.0.2.BUILD-SNAPSHOT

These manual updates are no longer required as of recent changes
to buildSrc and its generatePom tasks.  Now, when the project
version is changed in gradle.properties, generatePom will notice
and fire.  Previously, generatePom did not consider gradle.properties
as input for incremental build purposes; now it does.
