Revise test suite after moving Harvester properties to metacat.properties.

Initial suite of JUnit tests for Harvester code

JUnit files for tseting Harvester code

Added the EventLog functionality to the servlet as action=getlog. Valid parameters are ipAddress, principal, docid, event, start, end. All parameters can be repeated except start and end.

Partial implementation of a query facility for the access log. Need to fix problems with the date filtering, and tie this into the servlet action when completed and tested.

New EventLogTest modifying the log call to exclude revision.

Added classes for basic event logging support. These classes write log entries to the database connection. Still to do: query the event log, write oracle sql code (postgres is done), possibly allow the log to be archived to a text file, and possibly do the dtabase writes asynchronously via a caching mechanism.

Added a simple action for finding out the current metacat version. The information is pulled from the property file, so be sure to update the version in the property file before shipping a release.

Changed printAttributeQuery() to no longer depend on the xml_index table. Now, if useXMLIndex is false, the method will use a recursive query on xml_nodes to match paths instead of using xml_index.

Created new printExtendedSQL function that can get the extended
return fields using only xml_nodes and not xml_index. One
step closer to eliminating the dependence ofn xml_index.
