S-Pipe download

v2.2 [Jan 17, 2013]
1. Changed the caption on the "Cold Water Piping" and "Hot Water Piping" windows to "Cold Pipe Data" and "Hot Pipe Data" in order to match the user's manual, the help file and the toolbar button and menu captions.
2. Fixed a bug on the Number input on the Cold Pipe Data and Hot Pipe Data windows, where if you clicked the dropdown help button beside the input to display the dropdown help window, and then clicked that same button again to close the dropdown help window, the names of all the nodes of that kind in the project would be changed.
