Ship Odyssey: Finishing a site with 0 rats now causes game over.
Fixed a bug with the rat stepper starting at 0. (serious issue for mission 1). All ship controls disable themselves during a rat drop now, for consistancy. Hook stepper min value temporarily increased to 1 to combat animation bug.

Binary Changes:
-CraneAnimation: when the crane cannot be dragged, it no longer gives the user a hand icon.
-wood_panels (ship controls.swc) : A large 'Send 100 Rats' button was put in place for mission 1.
