Changed name of abbreviations file to a .js extension to avoid Chrome complaints.
Moved assignment of abbreviations to abbreviations.js to shrink cite.js (very slow to edit).
Created a ZAFQ namespace to hold abbreviations.
Cleaned up definition of (reduced) ZOTERO namespace
Refactored code to:

1.  Provide a stripped down Zotero namespace which provides Zotero.getAbbreviation
2.  Wrapped Zotero code in a ZAFQ namespace
3.  Wrote a file MakeZAFQ.bat to build wrapped abbreviation code into zafq.js
