Tested incremental DNSSEC signing / 2019-10-17

I noticed some really unused records in one zone which is now DNSSEC signed. For example I still had gplus.idefix.net to point at my Google+ page.

So I removed them and did the signing after increasing the serial number. Indeed the records that had no update kept their original signature and the records that where changed (such as the SOA because of the serial number) were signed with new signatures.
