Story: Add support for displaying contributors:

- Refactored the code to loop over an entity reference field and load
  all IDs into a shared helper, sw_load_referenced_entities().
- Use that to load all the contributor terms.
- Copied sw_contributor_sort() from D6 to alphabetize by last name.
- Use sw_get_entity_label_multiple() to add the right delimiters.
- Inject it directly into $variables['content']['contributors'].
