/*
  Thanx to Faith Healer for icons and help, Unregistered for his plugins (variables, AAA :p),
   mistag for GamerStatus,  BigMuscle for his code to use AAA
  Thanx to Tornado, orignal developer of AwaySys.
  Please note that some code from the Miranda's original away module (SRAway) is used around
  AwaySys. i tried to mention it wherever possible, but i might have forgotten a few. Kudos to Miranda's authors.
  The Read-Away-Msg part was practically copied from Miranda, not proud of it, but since i really can't see how can i make it better, there
  was no point in rewriting it all.
