#390 Aspect ratio changes as you type

[Frank Markesteijn]

In the crop tab the aspect ratio combobox changes the crop mask as you type, it is the only widget in UFRaw that does that, in all other entry widgets you have to hit tab, enter or return first or move focus away from the widget. It was mostly by trial and error and searching the web that I found the solution, you may want to make certain that everything is as it should be with this patch.
