Floater fixtures: the grab-point test and the wiring verify run over a moving well

Browse source 
PickupTests builds the zone over a sun and a planet on a rail, asserts the field differs between the ship's point and the item's and between start and end of the run, and checks each grab event at the zone time it was published. DrawnPoseWiringVerify gets a sun and a planet near the pickup and mine, requires the field under each to move with the drawn time, and checks the pickup's y as well as the mine's. Not compiled or run yet.
