Start button functionality (#21)

* srvPublishToSubscriber

Pressing Start from the app now sends the user to the Power Off screen.

* *hax check

As per Sono, checks whether the current environment is *hax. If it isn't, it goes to the home screen; otherwise, it restarts the console.

* Bugfixes

This may work?

* Revert "Bugfixes"

This reverts commit 7c382d719ac9f50af17d117f177c8bede75941f1.
