InterfaceText now defaults to null instead of {en:""} which
was awkward to deal with in the frontend.
As specified:
- label is InterfaceText
- type is a string and must be a one of the recognized types
Updated example for the hypothetical variant of Template:Unsigned
and removed other no longer needed example.
HTML output has been revised per conversation with Trevor,
James and Timo:
- Not sortable.
- Add label to html output.
- Aliases in the main parameter column (one per line),
but muted in styling.
- Add type to html output.
The css module styles content from the server, not content
generated by javascript. Moved module to position => top to
fix flash of unstyled content.

Registers a parser tag <templatedata> that should have a JSON
blob as content. The blob is then validated and normalised when
MediaWiki parses the page (e.g. during save and preview).
If there are validation errors, the save is aborted from the
extension hook and an error is displayed.
If all goes well, the normalised blob is stored in the database
(which can be retrieved through the API). And an HTML
representation of the template parameters is returned to the
wikitext parser to show where the <templatedata> was in the page.
The blob format is specified in spec.templatedata.json and
is validated in TemplateDataBlob::parse.
