Chat Systems 4.1.1

Upgrading from 4.1.0

• Set VERSION=4.1.1, pull both images and restart api, realtime and frontend together.
  There is no migration and no new setting. The desktop app updates itself to 4.1.1: it finds the
  release within six hours, or at its next start, and asks to restart.

Fixed

• Notifications from the desktop app pop up on Windows. They were sent under PowerShell's app id
  instead of the app's own, which Windows does not show as the app's banner.
• In the desktop app the sign-in page reads "Sign in to" the server's name and asks only for
  your email and password, or SSO. It used to ask for the server's address again, which the
  app already had, and offered to connect to a different server from inside this one's window.
• In the desktop app, ⌘1 to ⌘9 (Ctrl on Windows) open the first nine workspaces on the rail, in
  the rail's order. They used to switch between servers, so with two servers only ⌘1 and ⌘2 did
  anything. The Workspaces menu lists the same entries, and each rail tooltip shows its
  shortcut.
• The desktop rail shows each workspace's uploaded icon instead of its initials. The rail
  loaded the icon without the server's session, which the server refuses; the server's page now
  draws it and hands it to the rail.
• Joining or leaving a workspace shows up live. Someone who accepts an invite now sees the new
  workspace in their other tabs and in the desktop rail without a reload, and the members who
  stay see the member list change when someone joins or leaves. Before, only the person who
  left was told.
• A channel's member count and member list refresh when they change. The channel header loads
  its members, pins and bookmarks in one request and kept that answer for five minutes, so
  after the first half minute a refresh got the old list back.
