I've added double-signing support to cdimage, and re-signed everything with both old and new keys. For good measure I've also updated https://help.ubuntu.com/community/VerifyIsoHowto.

(In the hope that apt does not chose on signatures it cannot verify, otherwise the publisher would need to stop signing with the old key as well.)
