Bug compatibility patch

The initial value of iImage and iSelectedImage, which is -1, coincides with
_IMAGECALLBACK. Normally it should be OK as we keep track of a callback mask
for each treeview item. But intermixed with a bug in native comctl32 bad things
can happen such as this one.

If an app never sets the iImage(or iSelectedImage), but queries for this value
anyway with TreeView_GetItem, instead of failing the call, native
implementation just sets the field to 0. This of course is buggy bevavior, but
if we don't set iImage and iSelectedImage explicitly, zero initialization done
in Alloc happens to take care of that.
