Bug 16436 - Allow action logs to be logged to the koha log file

Test Plan:
1) Ensure that your Koha::Logger configuration is in good working order
2) Apply this patch
3) Modify the first line of your log4perl.conf file from:
    log4perl.logger.intranet = WARN, INTRANET
   to
    log4perl.logger.intranet = INFO, INTRANET
4) Change a system preference setting
5) Note the new line in your log file!
