The no-strand rule now asks whether the ship could leave the
destination on a full tank where fuel is sold, or on what is left
after the leg where it isn't. Emergency fuel is offered to an idle
ship that can't reach anywhere when the player can't afford the
shortfall: the cheapest leg's fuel at 2.5x the local price.

Ships get a tank capacity and a burn rate instead of range and fuel
cost; locations get a fixed fuel price and a sellsFuel flag instead of
the launch cost multiplier. A leg burns burn rate x the economic
distance of (distance / origin factor), and reach is a full tank's
worth. Tanks are sized so every reach answer is unchanged.

Positions, distances, range checks, trip times, fuel and the no-strand
rule no longer take a time argument; the 48-hour no-strand margin goes
with it. Tests now check that a route's pay, trip time and fuel are the
same whenever it is offered or flown.

Locations get fixed polar coordinates (the Moon as an offset from
Earth) and astronomy-engine is removed, so positions now come from
content. Ranges move into CR-015's reach bands for the fixed distances,
and the Lighter's price drops to 36,000 to keep the balance targets.
Date-sampled tests become yes/no.
