• (kg) fixed bug Appender::DBI where it was consuming the message
  array before other appenders could get to it
  
• (ms) changed config_and_watch to ignore clock differences between
  system time and file system time (helpful with skewed NFS
  systems). Added Log::Log4perl::Config::Watch.
  
• James FitzGibbon james.fitzgibbon@target.com: Added support for
  optionally restricting eval'd code to Safe compartments.
  
• (ms) allow/deny code in configuration files should now be controlled
  via the accessor Log::Log4perl::Config->allow_code(0/1).
  $Log::Log4perl::ALLOW_CODE_IN_CONFIG_FILE is still supported
  for backwards compatibility.
