bidi support test program

[Shachar Shemesh]

Hi all,

Attached is a simple program to test whether the Win32 API supports BiDi 
reordering. Some packagers asked me for such a utility in the past, so 
they can make sure that their inclusion of ICU worked, and without 
forcing them to actually understand languages that are all Hebrew to them.

I'm not sure whether it would be necessary to include this utility 
inside the Wine soure, or how to do so. This is not exactly a test, as a 
failure is totally justified under some circumstances.
