Patch Notes: Steadier towns when the servers are busy

Homes and towns

• When the servers are under heavy load, your game now waits longer between tries to load a town's homes, instead of asking again every 10 seconds. That helps the servers recover sooner.
• Loading a town's homes now costs the servers half as many database requests.

What's Changed

• HOMES-SHED: the busiest route one D1 request where it was two; the siege question answers a throw; a town unanswered backs off by @Lattymoy in #881
