Implemented a fix of crew movement, only to discover that the getPath stuff doesn't work at all with the location sockets!  Derp herpleton.

1: Check Destination for availability
2: Check path, and save the next step
3: If spot not reserved:
	3a: Reserve spot in CrewIndex
	3b: Set Spot in CrewTravelerIndex
	3c: Set crew previous to crew's current position
	3d: if nextStep == -1, set previous location to -1, and
	    crewTravelerDestination of the destination to -1
4: Incremental Movement
	4a: set Crew current location to Next Step
	4b: Increment Movement value by 0.2
	4c: if previous location == current location, repeat step 4
