Python Universal Library bug fix

[bartonc]

With the current release of Measurement Computings Universal Library, the UniversalLibrar y.py module is broken. Here is the fix:

def cbGetStatus(BoardNum, Status, CurCount,
				CurIndex, FunctionType):
	"""Returns status about potentially currently running background operation"""
	Status = ctypes.c_short(Status)
	CurCount = ctypes.c_long(CurCount)
	CurIndex = ctypes.c_long(CurIndex)
## Legacy call doesn't work with current cbw32.dll
##	CHK( cbw.cbGetStatus(BoardNum, byref(Status), byref(CurCount),
##						 byref(CurIndex), FunctionType))
	CHK( cbw.cbGetIOStatus(BoardNum, byref(Status), byref(CurCount),
						 byref(CurIndex), FunctionType))
	return Status.value, CurCount.value, CurIndex.value
