New image controls

[José Roca]

As the PictureCtx control doesn't support many types, because it is based in the outdated IPicture interface, and the ImageCtx control, based in the undocumented interface IImgCtx, used by Internet Explorer, doesn't stretch images propertly if Internet Explorer 8 is installed (Eros has told me that the image is repeated instead of stretched), I have written two new image controls to replace them: GdipImageCtx, based on GDI+, and FreeImageCtx, based in the FreeImage library.
