determine jsonld context to output from HTTP Accept header, not path

[ndushay]

• [x] OA dated context url in Accept for jsonld

  Accept: application/ld+json; profile="http://www.w3.org/ns/oa-context-20130208.json"

• [x] OA generic context url in Accept for jsonld

  Accept: application/ld+json; profile="http://www.w3.org/ns/oa.jsonld"

• [x] IIIF context url in Accept for jsonld

  Accept: application/ld+json; profile="http://iiif.io/api/presentation/2/context.json"

• [x] context specified for non jsonld (test that it is ignored)

  Accept: application/x-turtle; profile="http://www.w3.org/ns/oa-context-20130208.json"

• [x] json profile specified incorrectly (3 context urls) - be nice and accept it

  Accept: application/json; profile="http://iiif.io/api/presentation/2/context.json"

• [x] json format (3 mime types possible) + Link (3 context urls possible) + optional type

  Accept: application/json Link: http://www.w3.org/ns/oa.json; rel="http://www.w3.org/ns/json-ld#context"; type="application/ld+json"

in all three flavors (per http://www.w3.org/TR/json-ld/#interpreting-json-as-json-ld) type=blah is optional in Link header (refers to type of context doc) the context url should be included in a plain json doc returned

• [x] json format with no Link (missing header, empty string in header, missing rel, missing first part ...)
• [x] json format with unrecognized Link Url
• [x] jsonld with Link Url (be nice and honor it)
• [x] non-json format with Link Url (Link ignored)

- [ ] and NOT part of the path or params (i.e. remove this code and tests)

For:

• [x] #show controller action
• [x] #create controller action

And (as discussed) accept in Content-Type for POST/PUT. Should definitely not be part of path or params, as this is the same resource just a different representation.

@azaroth42 says " You might get other URIs too I guess, and while F4 might deal with that we could reject them (at least for now) for Triannon"
