WidgetListRow derives from Image, but init calls AWindow.init instead of Image

[sketchycode]

Line 51 of widgetlist.lua, I believe you intend a row to derive from Image. But on line 518 (the WidgetListRow init() method) you call AWindow's init, as opposed to Image. This leaves some of row's image-based properties uninitialized.

I found it when trying to use different images for row's background image. It's a quick fix (modify line 518 to call image.Image.init(self, gui)), just thought you'd like to know.
