Release 0.6.1-rc.1

0.6.1's first release candidate: certificates for other hosts (jarl cert
get, cert schedule, the certificates grant), certificate export, the
missing PTR list, links to a zone in other views, one-view tokens with
linked zones, PTR records and overrides in linked zones per view, the
registrar and DS guidance for subdomain and reverse zones, the stats
heatmap and cname_chain fixes. Upgrading a 0.6.0 database was tested.

 ### Upgrading
 
+- Tested: a 0.6.0 install with views, linked and reverse zones and
+  statistics, opened by 0.6.1-rc.1: every zone, record and view kept,
+  named answered as before, and the new grant and limits worked.
 - The database gains a migration (certificate owners, per-user
   certificate limits, certificate downloads). Going back to an older
   version afterwards means restoring a backup made before the upgrade.
