ca-certificates (20130610) unstable; urgency=low

CAcert root and class3 certificates are now installed as individual
files, no longer as the concatenation of the two. The certificates
are installed as cacert.org_root.crt and cacert.org_class3.crt for
ease of identification.

Remove obsolete debconf.org CA.
Remove obsolete SPI CA certificate expired in 2007.
