Liquibase Logging Extensions

Two extensions to liquibase that allow for control of logging.

1) Simple extension that uses log4j logging instead of System.out.

Just include the jar in the classpath, and liquibase will automatically use it. To control the amount of logging add the following to your log4j.xml file

 <logger name="liquibase.ext.logging">
     <level value="INFO"/>

2) Same extension using slf4j
