revise "document" and "manuscript" item types

[erazlogo]

Possible steps to fix this (would need revision in CSL as well as Zotero)

1. Document:

a) rename as "published document"

b) add "place" - to enter place of creation/publication

c) add "type" - to enter the type of document

d) set "published document" as a fallback for all published documents instead of "book" because there have been ​problems with "book" as a fallback

2. Manuscript

a) rename as "unpublished document"

b) add "institution" field, to enter the name of the institution where, say, a working paper was drafted (but not published), for example:

1. Clark, “Should the IMF Become More Adaptive?” Working Paper WP/96/11 (Washington, DC: International Monetary Fund, 1996).

c) add "number" field to number working papers:

Ferber, R. “Family decision-making and economic behavior.” Faculty Working Paper 35. College of Commerce and Business Administration, Univ. of Urbana-Champaign, 1971.

c) set "unpublished document" as a fallback for all unpublished documents

Revised the description to suggest revisions that make most sense to me but this should be resolved w/ Bruce before deciding on a final solution. See also a relevant ​forum request.
