Final commit (I think) to get update to solr getTerms() to work on gs3 checkout. The solr-jdbm-demo collection needed to be rebuilt with the changes to the index. This time added in other .xml files from the lucene/solr upgrade to the colleciton, and updated schema.xml and solrconfig.xml. This last is especially necessary as it uses the new Greenstone custom SearchHandler to get getTerms() to work.
