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