More ActiveX stuff. Can now automatically catch callbacks (events) from the

COM object.  I actually create a new class on the fly that derives
from wxWindow, the COM CoClass and others needed to make it all work.
The resulting class can be instantiated just like wxWindow, used in
sizers, etc.  It also responds to all COM method calls, properties, etc.

-ActiveXControl sample usage.
-
-Based on original code by Willy Heineman, wheineman@uconect.net, 14 February 2000
-
-ActiveXControl provides a simplified wrapper for creating activeX
-controls within wxPython GUIs.  It allows you to include the activeX
-control in a sizer, and includes a flag to prevent redrawing the
-background behind the control (reduces the annoying flicker on
-Win32 systems).
