New Flow technique

In line with the corebook tweaks that make multiple initiative passes more accessible, this revision adds a new Flow technique, Ultrametabolism (Automorphics; no prerequisites).

While maintaining Ultrametabolism, your Ganzfeld can choose, at the start of each combat round, to take one box of Stun damage in exchange for one of the Go-Again conditions — or one box of Injury damage for both of them — during that round.
