util_trayHiddenChange, which means an API change. In board, calculate bottom of board based on bottom of tray when tray is hidden, and round so that it's an exact multiple of cell height. In wince, take advantage of the new parameter to fix the scrollbar so that very constrained boards can be scrolled even when the tray is hidden.
