Patch for full resolution icons.

[Laurence Hygate <loz flower powernet co uk>]

The attached patch changes the way the EditIcon builds its icon. As it
stands it reads it as a clip from a scaled image. With this patch a copy
of the unscaled image is kept in memory and that is used as the source
of the icon. Having to know how to do the scaling feels a little icky,
perhaps it should be returned by the PxbufUtils.LoadAtMaxSize method.

cheers
