dded a space following the container-title.  I was finding that conferences were running together with Conference Name.  Hmmm.  Probably should just not do conference name if proceedings is available.
Changed In to lowercase (as in in Proceedings of ...) to match practice at MISQ.  Editor there referred me to this article: http://www.misq.org/skin/frontend/default/misq/pdf/Abstracts/ReineckeBernstein.pdf for additional guidance on citation.
Adjusted some date handling for MIS Quarterly.  Added "speech" (for Zotero Presentation) to exclusion list in issued.  Added date to publisher macro (since MISQ wants to see the dates of a conference for both Proceedings (paper-conference) and Presentation (speech).  Unfortunately Zotero's parsing of dates precludes MISQ's preference for the date range for conferences.  Probably would need to pass through an unparsed date string (e.g., August 9-14 or July 31-August4).
Adjustment to get a comma after container-title.  MISQ prefers this for Conference Papers, Presentations etc.
Changes to ensure comma after titles section.  In particular (eds) wasn't getting a comma after it.  The trouble is that articles don't have a comma after the container-title (journal name) and the locator, but everything else does.  Effected this with a new macro for container-phrase.
Adjusted to use more standard page setup.  MIS Quarterly doesnt accept first page pages parts, so you are going to need the whole page range anyway.
Fixed missing comma and space on pages.
Fixed date-part without surrounding date (and thus failing validation), for speech and paper-conference.
