Changes on 10-18-11:

• Fixed a bug that might cause you not to get insurance payments and/or might create a ghost ship if a Praelor destroys your ship. Probably only affects people who auto-deposit into their insurance fund, but I can't back that up with any facts.
• The SECURITY display will now classify fuzzy creatures and babies as 'probable lifesigns' rather than regular lifeforms.
• Added a hatch lifeform discriminator upgrade. Utilizing advances in sensor technology, this upgrade allows the hatch to seal itself against those whose lifesigns register below human standard. In a nutshell, it won't let anybody in if they're carrying or leading a baby. The only exception is the owner of the ship, who can do whatever (s)he wants to.
• Also added the DISCRIMINATE commands to the control room and, for your convenience, to the outside of the ship (DISC <shipname>) to toggle the discriminator on or off.
