• (ms) perl 5.005_03 fix for l4p::Appender::Synchronized
  
• (ms) Fixed a bug in 0.39 (thanks to James King for finding) which
  caused composite appenders like Synchronized to just use
  SimpleLayout. With the fix, composite appenders are now relaying
  messages unmodified to their delegates, which can then apply
  any layout they desire.
  
• (ms) Added file_open(), file_close() and file_switch() to
  l4p::Appender::File
