Model loading; overlay properties earlier

Browse Source 
This is to permit an <overlay> section in <model> to be present whilst the rest of the model is loaded - otherwise the overlay is only present after the model is loaded;

e.g. to allow a model specific registration to be applied to a shared model;

    <model>
        <overlay>
            <texture-file>island_68.png</texture-file>
            <carrier-name>Nimitz</carrier-name>
            <carrier-registration>CVN-68</carrier-registration>
        </overlay>
        <path>nimitz-class.xml</path>
    </model>
