Obfuscate the maintainer address, and allow PKGBUILD-only releases

The Maintainer line uses the usual AUR form (asger at weircon dot dk)
instead of a raw address that spam crawlers harvest. The AUR workflow
can now also be started by hand with a version and pkgrel, so a fix to
the PKGBUILD alone can be published without a new upstream release.
