MoveFileW fix

[Roderick Colenbrander]

As explained on the wine-devel list moving of files to a different volume was 
broken in Wine. According to MSDN this is allowed. This patch fixes that 
problem.

The other thing it fixes is that it now allows moves of directories as long as 
the directories stay on the same volume. Before no directory moves were 
allowed.
