#24 Made log4j the default logging framework

[Scott M Stark]

The org.apache.log4j framework is now the default
logging framework. The jboss.conf come configured with
the Log4jService mbean setup to initialize the log4j
framework using the logj4.properties file found in the
JBoss config directory. The Log4jService continues to
bridge messages logged via the legacy

The org.jboss.logging.Log and Logger classes have been
decprecated. Existing JBoss services derived from the
org.jboss.util.ServiceMBeanSupport class that use the
log instance var are really logging through a log4j
Category. A log4j Category object instance var has
been added to the ServiceMBeanSupport to allow
services easy access to the log4j Category object.
This Category instance is derived from the service
getName() method value.
