CQL-Java, version 0.5 - Changes

Changes between versions 0.4 and 0.5 of the cql-java distribution:

• Add an extra back-end method,

  		byte[] toType1BER(Properties config)
  	

  which generates an opaque BER-encoded PDU suitable for forwarding to Z39.50 server as a pasrt of a searchRequest APDU. This was contributed by Ralph Levan <levan@oclc.org>
• Add srw.resultSet support to the toPFQ() method.
• Add new resultSetName() method to CQLNode and its subclasses, returning the name of the referenced result-set for a node that is just a result-set reference, and null for anything else.
• Change regression-test rules for Adam's compiler to use his new front-end cql2xcql instead of the old cqlparse3.
• Change the names of the anchoring properties in etc/pqf.properties and the CQLTermNode code that examines them, in accordance with Adam's PQF-renderer's behaviour. This gives more flexibility in terms of generating attributes for end-of-field anchoring. Various other minor tweaks to the pqf.properties file, mostly to the comments.
• Change the capitalisation of the project name from ``cql-java'' to ``CQL-Java''. That doesn't really make any difference to anything: in particular, file-names such as cql-java.jar remain the same.
