Artist, label, and place can already be searched by area's name, but it would be useful to allow searching by area's MBID in case the name would change (either due to a real change or a style change).

Note: It is already possible to search for recordings by release's MBID, for releases by release group's MBID, and so on.

It requires adding the following fields:

• for artist:
  • aid
  • beginaid
  • endaid
• for label:
  • aid
• for place:
  • aid

Both old and current MBIDs for the linked area should return results.
