Identify the SPARQL-endpoint

[JLCochardSFA]

I think it would be interesting to see on the layout of a page generated by TRIFID which SPARQL-endpoint is assigned to this instance.
It will help when browsing through TRIFID-generated pages to place queries on the related endpoint.

Not sure if I get the point of the idea, what we were discussing is adding a "open in SPARQL" button or something like that on a resource so when clicking on the link it would open the SPARQL frontend and select the URI as subject.

Would that be it?

After discussion: Just provide an easy way to get the same IRI within a SPARQL endpoint. Could be as simple as simply opening a pre-defined SPARQL query in the correct endpoint.

Same as #60 basically, closing here.
