Auto-calibration of head tracking sensitivity

[Zulban]

Some kids can't move their heads very much, others more so.

When the game launches, it should begin learning about the limits of the user's head motion. If the maximum amounts they move starts to look to be very limited, rotation sensitivity should increase so they still have a shot at playing the game.

The bubble activity was meant to try and get that data while preparing air for the level...although those features have not be implemented in the activity at this time.
