update to citeproc-js 1.0.106

Fix a flaw in disambiguation logic that could result in a processor
hang, when a creator list with fewer names than its predecessor
required additional names to accomplish disambiguation.

Include the year-suffix as a sortable number string in dates used as
sort keys. Citations that include a year-suffix will now sort
correctly within the citation.

Restore XML to defaults before creating E4X objects.

Repair the processor demo page, which broke after revision 1.0.95.
