inform about current parser when losing connection

[Timtam]

When losing connection unexpectedly and unregistered by the game, the game will tell you that the old connection gets lost as soon as you reconnect. in that case the player doesn't know what he was doing before he lost connection. Thats especially important for soundpacks, because they cannot know if they should turn on duel music or lounge music, deck editor or room music or whatever.
