Support for fields on record api and ordering within facet groups

[mesemus]

record.record has an option "fields" to add any fields (dict field_name => field content) to record API. This can be used instead of "extra-code" to add fields on record (such as custom system fields, synthetic fields etc.)

Support for ordering within a facet group brings an option to specify the following ordering:

properties:
  propname:
    facet-groups:
      default: 3
      curator: 1

The propname will be the first facet for curator and the third one for other users
