Improve Data UI

[michamos]

The Data UI has several shortcomings:

• * Missing N citations button
• * Missing Literature button (linking to the record(s) in literature.record.$ref #638
• * collaborations should be displayed like for literature #640
• * authors should be displayed like for literature (and populated from the linked literature record)
• * DOIs with material=version or part should be ignored in the DOI dropdown in search results #637
• * Additional DOIs should be displayed under a Show all menu next to the main DOI on the detailed record #639

@michamos should the link to literature be both in search and detail? And just to verify, we are talking about literature.record.$ref right?

and also what I should display in the dropdown? The control_number? for example

        "literature": [
            {
                "record": {
                    "$ref": "http://localhost:5000/api/literature/1234"
                },
                "record": {
                    "$ref": "http://localhost:5000/api/literature/5678"
                }
            }
        ]

Link as button in search, text in detailed view. Yes, that's the correct field. For the detailed view, you can reuse what we do for seminars: https://inspirehep.net/seminars/2853636. For the dropdown you can also use the title if there is more than one (but there won't be for HEPData, so not an issue currently).
