Running the alley

Permissions, stuck lanes, restarts, removing a venue and tuning.

Permissions. nomadphysics.bowling.lane covers games and lane management, nomadphysics.bowling.place putting venues down and taking them away, and nomadphysics.bowling.give handing out balls and pins. Throwing a ball and the camera commands need none.
A stuck lane. Look at the lane's return rack with an empty hand while it is empty. That re-racks it, whatever went wrong. /bowling venue reset --lane=lane-3 does the same from a console.
Restarts. Every venue comes back by itself once its chunks load, and balls owed to players are handed back. Seats in a game live in memory, so a restart returns every lane to free play.
Taking it away. /bowling unplace disables a venue, clears the blocks its prefab wrote to air and takes it off the books. It does not put back the ground that was there before.
Tuning. NomadPhysicsBowling/NomadPhysicsBowling.json sets throw speed, ball and pin masses, rolling resistance, hook strength and the return delay. EnforceTurns makes a lane refuse a ball thrown out of turn instead of scoring it on the thrower's card.
