gnupg-1.4 is not developed actively anymore, and new software expects a modern "gpg" executable, which leads to pointless patches in the ports tree. Move the various users of security/gnupg2 to security/gnupg and zap patches that forced the use of "gpg2". Crusade started by edd@ (security/gnupg maintainer), gnupg->gnupg2 test reports from semarie@, giovanni@ and solene@, input and bulk build by sthen@. ok sthen@ edd@ (maintainer)
