In response to repeated concerns (*cough* Ewige up my-*cough*) about the value
in sinking NPC ships, I have redone the NPC Ship Crew internals so that their
experience values are somewhat less globally harsh. I may experiment with this
new system more in the future, but for now, it shouldn't be as easy for them
to be tuned to oblivion. Also, look for other rewards/benefits/opportunities
in the near future...
