Water Temperature Correction

I have modified chapter 24 on both sites to correct the mistake I made with the water in the greenhouse. The paragraph about the pan of water has been replaced with two paragraphs in which the water comes from the roof. It being winter, the water outside on the roof should be cold enough to transform Ranma. The means by which Ranma gets hit with this water is a little more contrived, but still within the bounds of the ordinary for the Ranma universe.
