emblemedicon: make GEmblemedIcon subclassable

Browse Source 
Hiding the object/class structs in the source file makes this class not
subclassable.

Move them to the public header, and add a property for the icon, so that
subclasses can just use

  g_object_new (DERIVED_TYPE,
                "gicon", icon,
                NULL);

to create an emblemed icon.
