ALL EDITORS V441 - PLAYERS TYPE THEIR ACCOUNT NAME (NO ACCOUNT LIST)
(V440 base: account window for Sunshine/Moonlight, one BaldurII_<account>.exe per account)

INSTALL (HOST PC)
  Close every BG2 window, run All Editors\SETUP_IN_GAME_ACCOUNTS.bat.
  Your Sunshine "Baldur's Gate II" Command stays the same (same file name).

WHAT A PLAYER SEES IN MOONLIGHT
  A small window: type your account name -> PLAY (or Enter).
  - Name found -> your BaldurII_<account>.exe opens, name filled in,
    type your password in the game.
  - Unknown name -> "No account named ... First time? Click NEW ACCOUNT."
  - Account already playing -> "... is already playing."
  No other account names are ever shown.
  NEW ACCOUNT -> plain BG2: CREATE ACCOUNT, LOG IN -> reopens as your copy.
  QUIT -> ends the stream.
