Teleport Player if Out of Bounds in games_fps

[ghost]

Description

Hello, this PR affects examples/games_fps.html. If the player jumps out of bounds (which is possible with jump velocity of 15), then the player capsule and player camera will be teleported back to their original vectors.

Please let me know if there's anything else I can add :)

EDIT: Adding a Githack link: https://rawcdn.githack.com/Uueuuuuu/three.js/8ee5d09c58ef88c2a95d18ad6800ce8c966fa8ef/examples/games_fps.html

EDIT no.2 : Should I not hardcode the vectors on line 427 and 428? They are referenced from the original on line 102.

Could you reset the orientation too?

@mrdoob Sure thing, I will do this shortly.

@mrdoob I've tested the code I just pushed and confirmed that these values are the correct ones. The view is familiar :)

camera.rotation.set( 0, 0, 0 );

Thanks!
