BMGame now provides extended die descriptions in its JSON representation

BMGame->getJsonData() now provides a new field, dieDescriptionArrayArray, which has the form:

    array(
        array(
            '8-sided die', 
            'X Swing Die (with 6 sides)'
        ), 
        array(
            'Twin Die (with 6 and 12 sides)',
            'Y Swing Die'
        )
    )

Addresses the back-end of #77.

Regarding the duplicated code warnings that have been added, these are the new dieDescriptionArrayArray fields, which just happen to be identical in games 8 and 9. Any ideas about removing this warning?
