Title: swissArmyJetpack.js toggles gravity for avatar

If the avatar stops over a voxel for more than 2 seconds then gravity is enabled. If the avatar steps off the edge of a voxel and there is more than 20 meters to the next voxel below then gravity is immediately disabled. Also, if the avatar moves very fast (> 25m/sec) gravity is disabled.
