Logging bug fixes + new functionality 

* Fixed names that were associated with CentralLogger to be fully
  qualified (to match behaviour present in slf4j + log4j +
  commons-logging + java.util.logging)
* Allowed for configuration keys "logger.*.appenders" to contain
  negative logger ids to remove an appender from that heirarchy in the
  configuration.

  Example:
  root.level=INFO
  root.appenders=rollLog

  logger.AUDIT.level=INFO
  logger.AUDIT.appenders=-rollLog,auditLog

  appender.rollLog.class=org.eclipse.jetty.logging.impl.RollingFileAppender
  appender.rollLog.filename=${jetty.home}/logs/central.log

  appender.auditLog.class=org.eclipse.jetty.logging.impl.RollingFileAppender
  appender.auditLog.filename=${jetty.home}/logs/audit.log
