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