created script for test database (in addition to the live one)
changed DB coordinates to access test database (since I am mostly using the RegTAP interface for Markus's test suite)
flexible build.xml with username, password and DB url properties allowing ingestor to be invoked on the target database
changed the manual harvester (an ivoa-console-util) to harvest to the test (and not the live) database
removed the need for a registry DB API in Repository, DBHarvestArea and DB_Harvest classes
