Title: Revoke subkey to force maven to use primary key for signing

See e.g.

http://central.sonatype.org/pages/working-with-pgp-signatures.html

"Some PGP tools generates sub keys and use them for signing by default, but to make Maven tools recognize the signature, you must use the primary key to sign your artifacts."
