ORCID and ROR updates

[qqmyers]

This PR:

• adds support for using the ORCID sandbox
• supports display when ORCID accounts do not have/share a last name
• fixes an issue (orcid and ror) with updated selections sometimes not being sent to Dataverse/resulting in author required/related errors
• changes the documentation to point to the gdcc orcid/ror scripts (vs QDR's)
• removes some duplicate code in the ROR script

As documented in the code, for hidden input fields, I've seen that using the jQuery val() method gets the new values sent to Dataverse consistently while using attr('value', ) sets the value attribute for the input so it can be seen in the browser console. Neither does both. We nominally only need the value sent to Dataverse, but I've used both methods to hopefully simplify debugging a bit. I don't fully understand why this is - I assume there's some different in event propagation for hidden inupts.
