**  Abandon Ship
**
**      The ship is abandoned.  If your current ship is the Faire
**      Queene, or if your shuttlecraft is dead, you're out of
**      luck.  You need the shuttlecraft in order for the captain
**      (that's you!!) to escape.
**
**      Your crew can beam to an inhabited starsystem in the
**      quadrant, if there is one and if the transporter is working.
**      If there is no inhabited starsystem, or if the transporter
**      is out, they are left to die in outer space.
**
**      These currently just count as regular deaths, but they
**      should count very heavily against you.
**
**      If there are no starbases left, you are captured by the
**      Klingons, who torture you mercilessly.  However, if there
**      is at least one starbase, you are returned to the
**      Federation in a prisoner of war exchange.  Of course, this
**      can't happen unless you have taken some prisoners.
