[Bug 30205] Unity Editor is unable to move project files

I think I figured out what's going on. The Unity editor is calling
SHFileOperation and is checking the fAnyOperationsAborted field of the ops
struct, and this field apparently doesn't get reliably initialized to false for
successful calls.

The following patch fixed it for me, I can now successfully build projects.
