36**  Check for Condition After a Move
37**
38**	Various ship conditions are checked.  First we check
39**	to see if we have already lost the game, due to running
40**	out of life support reserves, running out of energy,
41**	or running out of crew members.  The check for running
42**	out of time is in events().
43**
44**	If we are in automatic override mode (Etc.nkling < 0), we
45**	don't want to do anything else, lest we call autover
46**	recursively.
47**
48**	In the normal case, if there is a supernova, we call
49**	autover() to help us escape.  If after calling autover()
50**	we are still in the grips of a supernova, we get burnt
51**	up.
52**
53**	If there are no Klingons in this quadrant, we nullify any
54**	distress calls which might exist.
55**
56**	We then set the condition code, based on the energy level
57**	and battle conditions.
