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.
