Setting Target Platform for Attract Mode in BigBox

[Chris Weaver]

Requesting the ability to set a platform/playlist/etc. for Attract mode to default to, so that if someone has gone to a buried subgroup it will always reset to a default when left alone. I take my setup to large events often and this would help so that people don't have to learn to navigate the menus and I can have it always on "All Games" instead.
