• (ms) [RT 67132] Applied patch by Darin McBride to allow for
  empty syswrite messages in the file appender.
  
• (ms) [RT 68105] Fixed init-hash handling of subroutine references,
  reported by Frew Schmidt.
  
• (ms) Mike Schwern noticed confusing DESTROY calls to clean up loggers
  and appenders (http://stackoverflow.com/questions/5914088 and
  https://github.com/mschilli/log4perl/issues/7), so I put on my
  hazmat suit and cleaned it up. Now perl's garbage collector takes
  care of disposing of logger and appender carcasses.
  
• (ms) Added Log::Log4perl->remove_logger($logger) to remove a logger
  from the system.
