15 **  Check for Condition After a Move
16 **
17 **	Various ship conditions are checked.  First we check
18 **	to see if we have already lost the game, due to running
19 **	out of life support reserves, running out of energy,
20 **	or running out of crew members.  The check for running
21 **	out of time is in events().
22 **
23 **	If we are in automatic override mode (Etc.nkling < 0), we
24 **	don't want to do anything else, lest we call autover
25 **	recursively.
26 **
27 **	In the normal case, if there is a supernova, we call
28 **	autover() to help us escape.  If after calling autover()
29 **	we are still in the grips of a supernova, we get burnt
30 **	up.
31 **
32 **	If there are no Klingons in this quadrant, we nullify any
33 **	distress calls which might exist.
34 **
35 **	We then set the condition code, based on the energy level
36 **	and battle conditions.
