OUYA: Shut down game on back key

The thought came to me last night while I was sleeping, that perhaps in the newer firmware that the testers supposedly have on their OUYAs, that the System button no longer acts like the home button when it is pressed twice.  Instead, it simulates a KEYCODE_BACK event.  If that is the case, then these two items on the initial critique would make a whole lot more sense:

3. Once you enter the controller diagnostics screen, there is no way to navigate out, forcing the user to restart the OUYA console.
4. System button is used as back button, and does not allow navigation back to the OUYA menu/system screen

Since it doesn't break anything, I've decided to resubmit rather than waiting for them to reject the app again if this is a problem.
