Wildcard support in SSL cert names and trust anchor support

Hi Pieter,

I added 2 small features to swede to make it work better with my environment. The first one is support for wildcard matching with the CN and SANs of a SSL cert. I also added support for specifying a trust-anchor file as this is useful when testing with internal domains for which no DNSSEC chain exists in the public DNS.

Thanks for this nice tool!

Regards,
Simon
