Update bulk tagger for collections

[jimchamp]

Adds new collection type to the bulk tagger.

After adding new collection tag named some-collection-identifier.

When changes are submitted, the collection tags are added to the form, with the collectionID: prefix, in the subjects array. For example, if the changes in the above image were submitted, there would be a collectionID:some-collection-identifier label in the affected works' subjects field.

New label with prefix is appended to the work's subjects list (underlined in red, above).

Technical

Testing

1. Create a new collection tag with the bulk tagger.
2. Add the tag to a work by pressing the "Submit" button.
3. View the updated work's subjects field, and verify that the new collection is present.
4. Verify that the new label has the collectionID: prefix.
5. Remove the new label via the bulk tagger.
6. Ensure that the work record has been updated, and that the collection subject has been removed from subjects.
