Subject: [PATCH] Revert "Quit if Android back-button is pressed 3 times within
 1 second"

This reverts commit 91848f0be635ef495b18600abd3a95afe3b7beeb.

This was prone to accidental usage. The user interface is now usable with touch input, so this additional method to quickly and cleanly quit the game is not necessary anymore.
