TorBirdy 0.10 enables the message pane on restart

With Thunderbird 17.0.2 on Windows 7 and the message pane disabled, TorBirdy enables the message pane.

Thunderbird does no longer remember the state of the message pane, which still can be toggled with F8. I assume TorBirdy to reseting it.

Since I don't see this risking something it should be safe to remember the state, therefore I report this as bug.
