Will you make it so the old command line still works?

>>
>> 6) The methods for setting the log level on the DatabaseConditionsManager were removed in favor of using the standard logging API.
>>
>> 7) Custom log level settings on various classes were mostly removed in favor of using the levels defined in the logging.properties classpath resource.
>>
>> 8) There are no longer individual "handler" classes created for each logger. There should be just one global console handler now, so the messages from different loggers should always show up in order.
>>
>> 9) Related to #8, all of the calls to "logger.getHandlers[0]().flush()" were removed as they should no longer be needed. The console output should be flushed predictably and automatically now.

>> 10) The default message format was changed so that the entire log record appears on a single line instead of two like before.

>>
>> Overall, the logging should now be much better organized and easier to configure, and it is more in line with how logging configuration is supposed to be done in Java applications, e.g. using the standard logging API and customizing the behavior via a properties file.
>>
>> You should definitely 'svn up' the hps-java trunk immediately to get these changes, as many files were changed and there is the possibility of (minor) conflicts having been created in your local copy.
