Patch for OLEClipbrd_IDataObject_GetData

[Sander van Leeuwen]

Hi,

Forte Agent was unable to copy text from the clipboard into the message body window because
of a bug in this method.
I'm not sure how Wine's clipboard implementation works, but handles returned by GetClipboardData
are not supposed to be valid after the app calls CloseClipboard (see MS docs). 
The attached patch makes a copy of the clipboard handle and passes that to the application.
Forte Agent frees this handle after it has extracted the clipboard data, so there's no memory leak.
