* do_after
Ports (most of) do_after from SS13.
Callers are expected to await the DoAfter task from the DoAfterSystem.
I had a dummy component for in-game testing which I removed for the PR so nothing in game uses do_after at the moment.
Currently only the movement cancellation is predicted client-side.
