Changed DBSAXHandler.run() to now use the new DocumentImpl.buildIndex() method
for populating the xml_index table. The new method uses a jdbc ResultSet
for populating the index rather than doing it with the DBSAXNode, so it is
faster and can be run at any time on any document. This will allow us to
rebuild the index for any given document, or for all of the documents.
