If a particular property is only used in a reference or qualifier (e.g. not in a main snak), then the value does not get linked by the authority control gadget

@Fomafix not sure how much need there is but no reason for this not to work.
I wasted some time already debugging why the gadget wasn't linking references on test.wikidata. In the end, this bug was the reason and had forgot about this.
The problem is the way property data is fetched (currently via api). It could instead be maintained by a bot, as a json / js page on wiki. Even better solution (imho) would be to have this as a resource loader module provided via Wikibase or another extension. That way, it could utilize more caching and be automatically updated when a property is edited.
