Landmark Shuttles (#8512)

The lifeless live again. Or in this case, what never actually lived here.

Ports Baystation12/Baystation12#17460 probably for real this time. What this allows us to do is create shuttles on runtime and make shuttles easier by just making landmarks and a shuttle instead of areas and shuttles. Also allows runtime landmark creation via flares or whatever AND allows shuttles to use different landmarks at will.

I removed most of the overmap stuff, I think. It shouldn't be hard to slam it in whenever we need to.

Changes:

    "Shuttle code has been completely reworked."
    "Shuttles can now be modified to have more than one destination."
    "Shuttles now have a takeoff sound."
    "You can now throw mobs against walls to damage them. A lot."
    "You now need a neckgrab to throw mobs."
    "BEING UNBUCKLED DURING SHUTTLE LAUNCH IS DANGEROUS! Don't do it."
    "Adminghosts can now interact with all shuttles."
