Liquibase 2.0 beta 4 logLevel bug

If I try tu use the logLevel option set to Finest, finer or fine I get this exception:

Migration Failed: Unknown log level: finest.  For more information, use the --logLevel flag)
5-ott-2009 15.49.18 liquibase.logging.JavaUtilLogger severe
GRAVE: Unknown log level: finest
liquibase.exception.UnexpectedLiquibaseException: Unknown log level: finest
        at liquibase.logging.core.AbstractLogger.setLogLevel(
        at liquibase.integration.commandline.Main.doMigration(
        at liquibase.integration.commandline.Main.main(

With 2.0, I changed the levels to off, debug, info, warning, and severe.  I changed the error message you are seeing so it lists them.

The change seemed more standard and better described what the levels were for.
