Added mod-null, mod-nyq-bench, mod-track-panel. Updated mod-script-pipe to use wchar_t* for version number.

+\class ModTrackPanelCallback
+\brief ModTrackPanelCallback is a class containing all the callback 
+functions for the second generation ModTrackPanel.  These functions are 
+added into the standard Audacity Project Menus.
+
+*//*****************************************************************//**
+
+\class ModTrackPanelCommandFunctor
+\brief We create one of these functors for each menu item or 
+command which we register with the Command Manager.  These take the 
+click from the menu into the actaul function to be called.

+There are several functions that can be used in a GUI module.
+
+//#define versionFnName   "GetVersionString"
+If the version is wrong, the module will be rejected.
+That is it will be loaded and then unloaded.
+
+//#define ModuleDispatchName "ModuleDispatch"
+The most useful function.  See the example in this 
+file.  It has several cases/options in it.
+
+//#define scriptFnName    "RegScriptServerFunc"
+This function is run from a non gui thread.  It was originally 
+created for the benefit of mod-script-pipe.
+
+//#define mainPanelFnName "MainPanelFunc"
+This function is the hijacking function, to take over Audacity
+and replace the main project window with our own wxFrame.
