Add linked structure_id definition save frame

[rowlesmr]

To aid in defining linked structure_id data names in dictionaries.

The description is wrong.

The capacity to elide a data name is dependent on it being a category key.

They're are use-cases where this is not the case; cf _model.structure_id

Yes, this save frame should only be for those data names that are keys. The ones that are not keys are worth keeping in full in the main dictionary, I'd say. And also, it can't be used for those data names that are in child categories and should refer to the equivalent key in their parent category instead of _structure.id

this save frame should only be for those data names that are keys.

maybe, saveframe name: "structure_id_key"?

I'll make a commit, feel free to revert

[jamesrhester]

There could be a second template save frame for the "must-link-to-parent-category-structure-id" case which leaves out the _name.linked_item_id entry.

Will investigate tonight

[rowlesmr]

Maybe better:

"The structure to which this category relates."

"The structure to which this category relates."

Actually, yes, that makes more sense.

Should be good for merging now. Also to stop some check failures in other dictionaries.
