LVDIRHOOK HookID    - only for directory & multi listviews

    ---- YOU NO LONGER HAVE TO DECLARE THIS MODIFIER. ---

If you do not declare it, the HookID will be the same as the GadID
if this gadget.

The HookID is a number of a  XLVDirHook  event which will be 
executed every time you change directories, or in an xLVHOOK

The Directory ListView will show you the file list, but it will
not show you what directory you are in.. You have to do this yourself,
using this modifier and the event it points to.
