Major spacepod overhaul. Allow's for two people per spacepod. Makes
prisoner transport viable via click-drag and new 'lock secondary door'
option.
Fox's suggested changes- Includes ability to lock pod from new entries,
But not the occupant. The secondary occupant can still get out by
will. Entering a pod with the nuke disk is now impossible. Cannot drag
people into pods; This means you can go on adventures with your buddy,
but, no shoving people into pods and ejecting them into space.
Minor change; You can load corpses into the space-pod, but not living
people.
