Add SwissSign to ca-certificates

[Roman Hoog Antink]

Hi there

The swiss biggest mail company "Die Post" uses Certificates from the 
SwissSign CA.

Please add the SwissSign Certificates to the ca-certificates package.

The official website is here:
http://swisssign.com/operations/neue-swisssign-issuing-ca-zertifikate.html

On that page the download link is mentioned:

The funny thing is, that the package description of ca-certificates 
claims, it includes all CA's from Mozilla. But it does not contain 
SwissSign Certs, while Firefox does.
