Ian/80 20

@nicolashery ready for review i worked one the items in this card https://trello.com/c/pw8nT1Bl/40-5-blip-80-20-fixes-to-interaction
I do like the idea of a more human sound to the messages -- but I think it should be consistent. We've got both first person ("I've run out") and third person ("Blip ran out"). And then we always follow it up with a third person message ("Blip is stuck"). I think the first person ones should probably change to third person.
