winedbg Unicode strings output fix

[Catalin Patulea]

Hello,

Here's the patch which fixes Bug #1558.
The bug is essentially winedbg not displaying Unicode strings correctly 
through DEBUG_OutputW. Fixed by adding a real Unicode-to-ANSI conversion 
and then calling DEBUG_OutputA with the new buffer.
(This behavior can be observed easiest in the x/u command.)

ChangeLog:
 - fixed winedbg Unicode string output
