A small update.

• Webcam tracking: your avatar's hands now turn with your wrists, and other players see it.
• Webcam tracking: an open hand now opens all the way, and your shoulders move with your arms.
• VR: Drop Portal works again. The hand you press it with keeps its laser on and aims the portal.
• Fingers that bent backwards on some avatars are fixed.
• Mirrors no longer lose players when Range is set short. Range now counts from the mirror.
