Allow overriding time to wait when trying to kill the application.

Three new registry entries can be used to specify a wait time in
milliseconds after attempting a stop method.

  AppStopMethodConsole
  AppStopMethodWindow
  AppStopMethodThreads

The default for each remains the same, 1500ms.

Thanks Russ Holmann.

 does not call TerminateProcess() it is possible that the application will not
 exit when the service stops.
 
+By default NSSM will allow processes 1500ms to respond to each of the methods

+Each value should be set to the number of milliseconds to wait.  Please note

+so the actual time to shutdown may be longer than the sum of all configured
+timeouts if the application spawns multiple subprocesses.
