Summary: CreateFile puportedly supports Transaction= but does not

Initial Comment:
The following code:

h = win32file.CreateFile(dst, 
                                 win32con.GENERIC_WRITE, 
                                 0, 
                                 None, 
                                 win32con.TRUNCATE_EXISTING if os.path.exists(dst) else win32con.CREATE_NEW, 
                                 0, 
                                 None, 
                                 Transaction=self.transaction)
        win32file.WriteFile(h, data, None)
        h.Close()    

fails with pywin32-214 because:

Traceback (most recent call last):
  File "C:\Users\cnelson\rbc\dev-01.00\Deploy\Installer\deployer\src\installer\_
_init__.py", line 115, in <module>
    i.copy_from_memory("This shouldn't be here", "test.txt")
  File "C:\Users\cnelson\rbc\dev-01.00\Deploy\Installer\deployer\src\installer\_
_init__.py", line 101, in copy_from_memory
    Transaction=self.transaction)
TypeError: CreateFile() takes no keyword arguments

Both the ActiveState docs and the docs at http://timgolden.me.uk/pywin32-docs/win32file__CreateFile_meth.html say that CreateFile takes a Transaction= parameter.

Message:
CreateFileW is the function you'll need for transacted operations.
CreateFile will eventually be merged with CreateFileW when we
finally go to a completely unicode build, but for now it's a separate
function.
