**Feature summary** It would be good to be able to set the `guid` element from the Cargo query.
Alternatively it should be exactly the same as the `url` element:
1. The `url` can be customised by the Cargo query.
2. Currently the `guid` seems to be based on a URL based in turn on the `title` element, even if that `title` element has been modified by a CONCAT statement in the Cargo query, i.e. the `guid` isn't necessarily a working URL).
**Use case(s)** (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution): See Benefits.
**Benefits** (why should this be implemented?): For some feeds the same wiki page might appear in more than one item, resulting in the `guid` not being unique at all. We need some way of ensuring it is unique.
