Disable fireball button when the phone doesn't know it's location or when it is too close to the player

This is a little trickier than it seems. Somehow you have to check both these conditions at a regular interval so that the button is visually disabled. For now, call a method to perform that check from onGameStateChange.

Bonus points if you display a TextView in place of the crosshair that says "Too close to robot. Cortex overload." or something like that when the eyeball gets too close to the robot.
