NOTIF : Files and dirs changes notifier

• When a notification event occurs, notif can launch a script.
  The script filename is defined with the command line option -x:"program_file"
  Ex.: notif -x:"..\tools\script_file.cmd" [...]
The path to the script must be relative to the current working dir.

  In the context of this new process, some environment variables are set by notif:

  NOTIFCMD_FIRED_EVENT

  This variable stores the event which triggered the notification.

  NOTIFCMD_FIRED_PATH

  This variable stores the monitored path for which the event occured as typed on the command line (e.g: ..\log).

  NOTIFCMD_FIRED_FULLPATH

  This variable stores the monitored full path for which the event occured (e.g: d:\home\ch\www\log\).

• An error is raised if log file is output in a monitored directory:
  Monitoring folders c:\www\* and down while storing log results in file "c:\www\logs\notify.log".
  notif c:\www\ -s -o:c:\www\logs\notif.log -e:fa
  This generates an error and stops: Output file must not be located in a monitored path.
