#757 PyIAsyncOperation has been renamed

[Xaav]

So finally after some months, I figured out the IasyncOperation compilation issues. This needs to be added to the top of PyIAsyncOperation.h:

#if _MSC_VER >= 1900
#include "Shldisp.h"
#define IAsyncOperation IDataObjectAsyncCapability
#define IID_IAsyncOperation IID_IDataObjectAsyncCapability
#endif
