Update CDLR in Zend_Locale to 23.1 

This is a big update for Zend_Locale to the newest Version of CDLR. There are a lot of changes in the specification of LDML with many deprecated elements. It would be better if someone else could make a code review before merging, although all unit-tests were passed well. see at least #6 #27 #87 

(There is a typo-error in my commit message - this should be "add missing VN to territory...")
