Parent ROM concept mame2003

[thelamer]

Full mame2003 sets look like a mess, metadata should be added for a parent rom and the frontend should support launching the parent into a submenu to launch the different clones.

Just ended up not showing clones if parent is present. Maybe down the line look at a submenu feature. Everything can be overridden manually if not using the auto scan feature stuff.
