Send mail with status of all submissions

(from chat)
in penta we had a function that listed all talks with current state, and put that in the emails
could do with something like that for next year, to add to the bottom of mesages
"The current state of all your submissions to his conference is:"
then list every submssion and its state

I actually think we could add that message to every message (and add schedule if known).
