Patch Notes: City stutter fix

Fixed

• Stutter in cities. Arriving in a large city, or walking out of a building in one, no longer freezes the game for several seconds. It was worst in Firefox. Thanks to ghandhikus for finding and fixing it.

What's Changed

• ROADS-MISS: the city stutter - a roads' day not ready yet is asked once a tick (ghandhikus's #889) by @Lattymoy in #895
• REVIVE-SIZE: the line's record revived by an edit in place, all or nothing by @Lattymoy in #897

Full Changelog: app-v0.1.8542...app-v0.1.8548
