Grab note fields from MARC records (including table of contents)

[tjowens]

The MARC translator should import various notes fields as Zotero notes:

This includes the 505 field (table of contents):

If we're going to save this, we should probably either create a Table of Contents field or put it into a note. Extra is a pretty meaningless field that we should probably remove so that we don't keep using it. Notes don't have any inherent meaning, either, of course, but at least they don't pretend to.

Changed the ticket to suggest creating a note instead of using the Extra field. I don't see enough value added to create new a item field for it but, when available, it's nice for search.

I've made the ticket more general: we don't grab the contents of any MARC note fields & it'd certainly be nice to have more than just the ToC (per forum discussion, linked to in the description).

Proposed fix: ​https://github.com/ajlyon/translators/commit/5f30bee25b8c3e32f2eae529aa8f3d9dc0c5f212

                // Extract note fields
                // http://www.loc.gov/marc/bibliographic/bd5xx.html
                // general note
                this._associateNotes(item, "500", "a");
                // formatted contents (table of contents)
                this._associateNotes(item, "505", "art");
                // summary
                this._associateNotes(item, "520", "ab");
                // biographical or historical data
                this._associateNotes(item, "545", "ab");

There are lots of possible notes-- these four seem most likely to be needed. Others can be added if necessary, but I don't want to flood libraries with unneeded notes.

this has been implemented.
