I'm currently implementing the multi-sig-functionality, guess I'll get that done over the weekend, GUI elements will follow next week.

@fellowtraveler and @jan
I think I can't place a new bid for the re-opened tasks on CIYAM because one can only apply once, so can you please enable them again for me?
I'm making good progress with Bitcoin Integration (when I find time to work on it), Bitmessage is something someone else can work on but if nobody will I'll do it next.
