Elliot Glaysher e9f09e32c1 king: put slogs in the muxed scrollback
If you connect to an urbit using the remote terminal code,
slogs would not be printed to them since they were hard
coded to be printed to stderr. This threads slog printing
to the terminal driver, and puts them in scrollback.

(It does not actually fix slogs being printed on one line.)
