Hyper-proof cooldown state

Kept the distinction between "argument" time and script time. I called the latter "time" instead of "milliseconds" because, well, it's just tenth of seconds.
Residual timeout is always stored in "nominal" time, not adjusted by hyper. I.e. if a button has a nominal timeout of 60 seconds and half cooldown had expired on reload, residual is stored as 300. In cooldown, Engine.setInterval makes the time flow with double speed
