Add a new simulation message and chat notification for players who won.
Avoid duplicate playerstate messages in the sim and GUI by triggering
changes with a function instead of a message.
Reveal the map on defeat/win exclusively in the player component
(instead of having a silly GUI proxy and doing it also in the
EndGameManager sometimes).
Remove the skipAlliedVictory argument from the player component, since
that shouldn't contain references to the EndGameManager, refs #3970.
Show a proper message box on win/loss and add the hint for hosts
disconnecting other players.
Do defeat/win procedure in the GUI when such a message arrives, instead
of checking onTick for playerstate changes.
Thus don't show that confirmation again on every rejoin.
Don't show a pointless message box if IsAtlasRunning.
Explain that the session.js variable is needed to avoid an
order-of-execution bug.
Select "observer" item when rejoining as a defeated player.
Remove an unneeded call to updateTopPanel.
This was SVN commit r18441.
