The toolbar order, favourites, and open panels were saved into
exp_legacy's PlayerData, which was never synced, and the file doing so
was no longer loaded. When a player leaves, the lua side now sends
Gui.toolbar.get_state as json compressed with helpers.encode_string,
and the controller stores the string on the player record.
When the player joins again the instance plugin sends the stored string
over rcon to exp_scenario.player_settings.receive_toolbar, which
decodes it and calls Gui.toolbar.set_state. exp_gui builds the toolbar
in on_player_joined_game, so it exists by the time the rcon arrives.
A string which does not decode, or a state naming buttons which no
longer exist, is logged and ignored rather than raising in the game.

exp_legacy recorded each player's locale in PlayerData statistics
which nothing read. The lua side now sends one ipc event with the
player's locale when they join and when they change language, the
instance forwards it, and the controller stores it on the player
record.
The Scenario section of the user page shows the language by name with
a flag made from regional indicator symbols. Locales with a region use
it directly, the rest map to a country through a small table covering
Factorio's locale list. Arabic, Catalan, Basque, and Esperanto have no
single country and get no flag.
