VR users can temporarily ghost by relogging

[AquaDraco]

Problem: Normal users using virtual reality can go into ghost form, observe people, etc., and still re-enter their living, real-life body afterwards.

How to reproduce:

1. Enter VR
2. Relog
3. You are now a ghost
4. Abuse your ghost powers by talking to dead players, observing the traitors, finding the syndicate shuttle, eavesdrop on your boss, etc.
5. Use re-enter corpse to re-enter living body

Solution: Either have the client reconnect to the VR body or the living one.
