iconfactory: Add scale info to GtkIconSource
GtkIconSource now has notions knows about scale, so it can correctly
fetch the icon at the right scale for ICON_NAME source types.
All default stock icons have been made to have a wildcarded scale,
so it's up to the GtkIconTheme to do the scaling business.
