[DCP-o-matic] KDM delivery CC: address

I know it was my own idea - but maybe it is better to make the CC: address a BCC: ? Because in general the KDM receiver shouldn't see it. No big thing, but... Or may just offer both, I think there is still enough space on that tab. Commercial KDM delivery emails usually have a bunch of recipients for internal and external reference. Sometimes half a dozen people receive an individual KDM Email. - Carsten
