Turn half-assed acceleration based movement in FPS controls into constant velocity mode to prevent oscillations around 0 velocity. Decrease touch controls time-to-destroy blocks from 1s to 500ms. Redo cameraDirection() with https://github.com/mrdoob/three.js/blob/master/examples/js/controls/PointerLockControls.js and a hacked up version for device_orientation_controls. Moved around some functions.
