Broken RPL Editor as a result of Phil's replacement of the Galaxy 'vrect' structure with Qt QRect [1-8-2008] ... FIXED.

It turned out that QRect was not a good replacement for vrect. QRect is defined with the upper-left and lower-right corner coordinates (X1, Y1, X2, Y2). The Galaxy 'vrect' is defined with the upper-left corner coordinates plus width and height (X, Y, W, H). With QRect, setting 'X' or 'Y' changes the width or height of the rectangle, but in vrect, it does not.

I instead made our own replacement class for 'vrect': Utils/PersistSizeRect.
