Adds an icon factory to the list of icon factories searched
by Style.LookupIconSet(string). This means that, for example, Image(string, IconSize) will be
able to find icons in factory. There will normally be an
icon factory added for each library or application that
comes with icons. The default icon factories can be
overridden by themes.
