Replace ORCID with type ID types

ORCID iD is specific for people, whereas the other values are not.

Proposal is to remove ORCID id and replace with a generic ID that can be typed (or at least have a regex for them):
* orcid id
* grid ID
* ROR id
* Ringold ID

then a user when specifying a credit simpy types a value in the ID field and (optionally) picks a type.
