Phase out JettyLog
Jetty uses slf4j, and so does Openfire since OF-53. As a result, there probably is no longer a need for org.jivesoftware.util.log.util.JettyLog
Let's see if we can remove this class and replace it with standard logging functionality provided by slf4j / log4j.
The class that redirected all of Jettys 'INFO' messages to Openfire 'DEBUG' output has been removed. Instead, a org.eclipse.jetty appender was added to the default Log4j configuration.
