Subject: Changed QE_DeleteBinding to delete all bindings on the given object
 if the eventString is NULL. This code was in TkWinEventProc. Changed
 TkWinEventProc to call QE_DeleteBinding. QE_GetAllBindings: stop searching if
 object was found since an object can only appear once in each BindValue
 chain. New QE_UnbindCmd allows unbinding all scripts on a given object.
