Patch Notes: Login fix, ports on the map and docked ships

Logging in

Fixed: logging in sent you straight back to the title screen. After two server restarts on October 4, everyone reconnected at once and the account service fell over under the load: sign-in failed and dropped you on the title screen. The service now does far less database work on every request, so a full server of players can log in together again.

Ports show on the Enhanced world map. Every port you've discovered has an anchor at every zoom, including the whole-bay view the map opens on. Before, anchors appeared only zoomed in, and only with Travel Options' "Only From Ports" on.
Easier to spot. The anchor is drawn darker, with a light outline, so it stands out on a busy coast.
The Ports filter button and its P key still appear only with "Only From Ports" on.

No more ships inside your ship. A ship you leave made fast at a port's quay keeps her berth while she's out of sight. Before, sailing back into that port could find one of the port's own ships moored right inside her.
Summon and docking agree. Neither brings a ship to a berth where one of yours lies unseen.
Online: another player's ship lying at a berth keeps it even while its captain is invisible at her helm.

Dying online now costs a tenth of the gold you carry, down from a quarter.
Online, every trip over land on the travel map is travelled rather than instant. Travel Options, its Cautiously and Inns options, and "ships only from ports" are always on online. Ships from a port and travelling to your party leader work as before.
With Climates & Calories on, rations in your pack are eaten automatically when you get Hungry, instead of waiting until you are Starving.

City walls no longer have gaps next to their corner towers. With Beautiful Cities on, the walls of most cities (Alik'ra and Chesterwark among them) had a 3-metre opening on each side of every corner tower that you could see and walk through. These now hold a matching section of the wall.

CITY-WALL corners closed; a tenth of the purse on death; no instant travel online; rations eaten at Hungry by @Lattymoy in #575
Login fix, ports on the map and docked ships: ACCT-RATE-MEM, PORT-MAP, BERTH-HIDDEN by @Lattymoy in #580
