Except in rare cases, macros that render more than one element should 
be avoided as sort keys, as they can lead to unexpected sorting in edge 
cases. Instead, use their elements as individual, consecutive sort keys.

Closes #31

Add version, tags fields to script, tests

This field would be used to filter tests. Althought currently this value
will convert to a string, assuming comma-separated tokens.

Partially addresses #17 and #25, this adds a "VERSION" field to the
processor.py script.

Syntax for the field value is: [version]:[tag].

Remove undefined macros from text

Fixes #23

closes #22

No longer needed, as it now points to files that don't exist.

…es as appropriate

Closes #15.

Also reported in #19.

This commit fixes a regex that is too greedy.

Until #17 is addressed, this borrows the ignore.txt list from the
citeproc-rs project, and adds two additional tests identified in #16.

This list identifies those tests that rely on undocumented modes in 
citeproc-js. 

The contents are simply one filename per line, for easy processing.
