• (ms) Matthew Keene mkeene@netspace.net.au suggested to have
  an accessor for all appenders currently defined -- added
  appenders() method
  
• (ms) Test case 041SafeEval.t didn't share $0 explicitely and
  created some warnings, fixed that with (jf)'s help.
  
• (ms) Added performance improvements suggested by
  Kyle R. Burton mortis@voicenet.com. is_debug/is_info/etc.
  are now precompiled, similar to the debug/info/etc. methods.
  
• (ms) Added a fix to have is_debug()/is_info()/etc. pay
  attention to on-the-fly config file changes via init_and_watch().
  
• (ms) Fixed bug that reloaded the config under init_and_watch()
  every time the check period expired, regardless if the config
  file itself had changed. Added test case.
