  Log Message:
  -----------
  Update POM for Sonatype OSS

This modifies the POM to inherit from the standard Sonatype OSS Parent POM.
The change also removes the <distribution> element, which isn't necessary
if we're inheriting from the Sonatype POM.

This also adds a release-sign-artifacts profile to automatically sign the
artifacts (required for Sonatype upload).
