Rename printer.gcode.action_emergency_stop() to action_emergency_stop(), printer.gcode.action_respond_info() to action_respond_info(), and printer.gcode.action_respond_error() to action_raise_error() in command templates. This simplifies the get_status() interface, as returning callable functions from that interface was confusing. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
