The `TaskControl` and `TaskReader` properties contain no information that can be used in serialized form, but they were added to the output anyway.
With this commit, the unwanted extra data is no longer emitted.
The logic is currently that the template is scanned for potential values, and those that are found are reported in the extra tag for the JSON.
A bit clumsy, but allows the user to choose specific fields to include in the reported data.
Integrated changes to support log-lines and to have a common shared module for reporters
