15 **  Automatic Override
16 **
17 **	If we should be so unlucky as to be caught in a quadrant
18 **	with a supernova in it, this routine is called.  It is
19 **	called from checkcond().
20 **
21 **	It sets you to a random warp (guaranteed to be over 6.0)
22 **	and starts sending you off "somewhere" (whereever that is).
23 **
24 **	Please note that it is VERY important that you reset your
25 **	warp speed after the automatic override is called.  The new
26 **	warp factor does not stay in effect for just this routine.
27 **
28 **	This routine will never try to send you more than sqrt(2)
29 **	quadrants, since that is all that is needed.
