broken arithmetic face to cell distance calculations

[wd15]

The two tests starting [trunk/fipy/variables/cellVariable.py@3037#L303 here] are complete nonsense! We used the same broken calculation to derive the answer as we used in [trunk/fipy/variables/arithmeticCellToFaceVariable.py@3037#L45 _ArithmeticFaceToCellVariable]. Thanks to William Gathright for rasing this issue [http://thread.gmane.org/gmane.comp.python.fipy/1458 here], he noticed that the gradients were broken.
