** Automatic Override
**
** If we should be so unlucky as to be caught in a quadrant
** with a supernova in it, this routine is called. It is
** called from checkcond().
**
** It sets you to a random warp (guaranteed to be over 6.0)
** and starts sending you off "somewhere" (whereever that is).
**
** Please note that it is VERY important that you reset your
** warp speed after the automatic override is called. The new
** warp factor does not stay in effect for just this routine.
**
** This routine will never try to send you more than sqrt(2)
** quadrants, since that is all that is needed.
