* The virtual reality turned component.

* Originally created to overcome issues of mob polymorphing locking the player inside virtual reality

* It relies on comically complex order of logic, expect things to break if procs such as mind/transfer_to() are revamped.

* In short, a barebone not so hardcoded VR framework.
