Make AkonadiJob work in two ways: * if it is given an item with an AddressAttribute, just send it. (this is handy when apps already have the item created.) * if it is given data and addresses, construct an item, give it an AddressAttribute, and then send it. (this makes AkonadiJob work like other TransportJobs.) Problem: where to create this item? (so this doesn't work yet.)
