  Description
  -----------
  This plugin for Miranda-IM notifies user of specified events (as incoming messages, 
  incoming files, incoming URLs or other events). This plugin is based on KeyboardNotify
  by me.
  It has many options allowing:
  a) To select on which events to react
  b) Under which conditions (eg: fullscreen mode, ScreenSaver running, workstation locked)
  c) To act only if the protocol receiving the event is under specified status
  d) For message events you can choose to be notified if the message window is open or not
  e) A notification feature allowing to be notified of pending events (unopened events)
  after specified period of time
  f) To select method for stopping the blinking (after x secs, if Miranda is re-attended,
  if Windows is re-attended, if all notified events are opened or when the notify conditions
  end)
  It was designed to be flexible and performing several different tasks.
  It also provides a service to allow third party plugins use its notifier abilities.

  Thanks
  ------
  - Pete for the numerous patches he sent, actively helping to improve the code and 
  functionality
  - UnregistereD for great help in solving problem with Windows activity detection
  - Slacktarn, Sir_qwerty and Tweety for giving great help with ideas (most of the new
  features included in this plugin were suggested by them) and testing
  - The authors of AAA, PopUp+, KeyScrollNotify, original KeyboardNotify, Neweventnotify,
  IEView, NGEventNotify for part of their code used in this plugin.
  - Miranda IM developers for this amazing program
  - all other people from Miranda community

  History
  -------
  0.0.2.2:
    [!] Fixed problem while trying to detect if message window is in foreground
    [*] Improved ListView control handling
    [*] Changed the default values (for the sake of new users)
    [*] More code optimization.
  0.0.2.1:
    [+] Support for Updater plugin.
  0.0.2.0:
    [+] New 'notify when' option: while defined programs are running (just like gamerstatus)
    [+] Extended the API to add two new services to disable and re-enable keyboards notifications (for use by bosskey plugin).
  0.0.1.2:
    [!] Fixed some compatibility issues with nconvers++ (thank you donatas for your help).
  0.0.1.1:
    [!] Fixed problem with Windows' activity detection under Win9x when using other plugins that do the same
    [!] Fixed crash caused by incoming authorisation requests when metacontacts was enabled.
  0.0.1.0:
    [+] Applied pete's patches (thank you very much for your great work)
        - Use of GetLastInputInfo when possible for detecting Windows' activity
        - Made Windows' mouse hooks also aware of mouse clicking
        - Made Miranda re-attended option react on windows restoring and ignoring mouse hovering an unfocused window
        - New option for message events to avoid blinking if message window is focused
        - Made the plugin handle metacontact's special issues
    [!] Use of the new message API for windows detection when possible
    [+] New message event option to check last message timestamp (requested by D46MD)
    [+] Possibility of choosing more than one flash until option at the same time
    [+] Possibility of selecting/unselecting protocols (requested by tweety, usuful to avoid flashing on some protocols as rss)
    [!] Changed behaviour of Preview button to make it independent of the rules' options.
    [!] Fixed Metacontacts recognition in checking and counting of pending events (thank you NirG for finding the problem)
    [!] Fixed problems with multiple instances of the plugin running (thank you tweety for reporting and testing).
    [+] New plugin API (thank you CriS for your ideas and great help)
    [!] Added Offline status to status check list (thank you Slaktarn for finding it).
    [!] Fixed problem with first message in Metacontacts recognition while checking for pending events (thank you again NirG)
  0.0.0.3:
    [!] scriver's message window detection (thanks D46MD for your great help)
    [!] corrected 'flash until' checking accordingly to pete's patch (thank you for this) 
  0.0.0.2:
    [!] nconvers++'s message window detection
    [!] checked window detection for srmm, scriver, sramm and srmm_mod
  0.0.0.1:
    Original version
