Add missing "do not disturb" param

[rozwell]

Since it's a basic functionality now, I think it should be enabled unless there's a reason not to?

[Jajcus]

Is this enough? Shouldn't jggtrans also translate XMPP dnd to/from the appropriate GG code?

[rozwell]

Seems to be. After adding this parameter, dnd works just fine (for few months already).

Sry, closed accidentally.

Thanks :)
