First use only user defined thruster groups when in pulse mode.

In TimeStep

Threshold = .9;
pulse_time = 1.0;
if (vessel->GetManualControlLevel(THGROUP_ATT_PITCHUP, MANCTRL_ROTMODE,
MANCTRL_ANYDEVICE) > Threshold) {
   if (!do_pulse) {
      start_pulse = simt;
      do_pulse = true;
   }
}

if (do_pulse) {
  if (simt - start_pulse > 1.0) {
    vessel->SetThrusterGroupLevel(rcs_pitch_up, 0.0);
    do_pulse = false;
  } else
    vessel->SetThrusterGroupLevel(rcs_pitch_up, 1.0);
