Listview notify_dispinfoT Messageformat

[Thorsten Kani]

Hello,
Testing showed that the current implementation of notify_dispinfoT 
doesnt work with W2K. (or at least not with SP4 (:   )
The attached patch corrects that our Listview doesnt display anything on 
native.

Following assumption proved to be wrong for the Message LVN_GETDISPINFOW:
/*
With testing on Windows 2000 it looks like the notify format
has nothing to do with this message. It ALWAYS seems to be
in ansi format. */

This time, only LVN_*ETDISPINFOW is patched, anything else is untouched.
-Anybody please tell me if you see problems with this Fix since i dont 
want to break things.-

Tho
