* Extend template entities with a script section
This allows making a trigger entity that triggers a few times a day,
and allows collecting data from a service resopnse which can be
fed into a template entity.
The current alternatives are to publish and subscribe to events or to
store data in input entities.
* Make variables set in actions accessible to templates
* Format code
