NOJIRA fix various importer issues:
	1. add truncateLongLabels option for preferred/nonpreferred label mappings to automatically truncate labels that are over-length
	2. modify XML data readers to support . and .. in XPath. Previously these had the default namespace applied to them which prevented evaluation
	3. Throw log errors when invalid list is specified in list item splitter
NOJIRA use md5 for cache key rather than crc32
