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."

-The overmap system allows adding new maps to the big 'galaxy' map.
-Idea is that new sectors can be added by just ticking in new maps and recompiling.
-Not real hot-plugging, but still pretty modular.
-It uses the fact that all ticked in .dme maps are melded together into one as different zlevels.
-Metaobjects are used to make it not affected by map order in .dme and carry some additional info.
-
-*************************************************************
-Metaobject
-*************************************************************
-/obj/effect/mapinfo, sectors.dm
-Used to build overmap in beginning, has basic information needed to create overmap objects and make shuttles work.
-Its name and icon (if non-standard) vars will be applied to resulting overmap object.
-'mapy' and 'mapx' vars are optional, sector will be assigned random overmap coordinates if they are not set.
-Has two important vars:
-	obj_type	-	type of overmap object it spawns. Could be overriden for custom overmap objects.
-	landing_area -	type of area used as inbound shuttle landing, null if no shuttle landing area.
-
-Object could be placed anywhere on zlevel. Should only be placed on zlevel that should appear on overmap as a separate entitety.
-Right after creation it sends itself to nullspace and creates an overmap object, corresponding to this zlevel.
-
-*************************************************************
-Overmap object
-*************************************************************
-/obj/effect/map, sectors.dm
-Represents a zlevel on the overmap. Spawned by metaobjects at the startup.
-	var/area/shuttle/shuttle_landing - keeps a reference to the area of where inbound shuttles should land
-
--CanPass should be overriden for access restrictions
--Crossed/Uncrossed can be overriden for applying custom effects.
-Remember to call ..() in children, it updates ship's current sector.
-
-subtype /ship of this object represents spacefaring vessels.
-It has 'current_sector' var that keeps refernce to, well, sector ship currently in.
-
-*************************************************************
-Helm console
-*************************************************************
-/obj/machinery/computer/helm, helm.dm
-On creation console seeks a ship overmap object corresponding to this zlevel and links it.
-Clicking with empty hand on it starts steering, Cancel-Camera-View stops it.
-Helm console relays movement of mob to the linked overmap object.
-Helm console currently has no interface. All travel happens instanceously too.
-Sector shuttles are not supported currently, only ship shuttles.
-
-*************************************************************
-Exploration shuttle terminal
-*************************************************************
-A generic shuttle controller.
-Has a var landing_type defining type of area shuttle should be landing at.
-On initalizing, checks for a shuttle corresponding to this zlevel, and creates one if it's not there.
-Changes desitnation area depending on current sector ship is in.
-Currently updating is called in attack_hand(), until a better place is found.
-Currently no modifications were made to interface to display availability of landing area in sector.
-
-
-*************************************************************
-Guide to how make new sector
-*************************************************************
-0.Map
-Remember to define shuttle areas if you want sector be accessible via shuttles.
-Currently there are no other ways to reach sectors from ships.
-In examples, 4x6 shuttle area is used. In case of shuttle area being too big, it will apear in bottom left corner of it.
-
-Remember to put a helm console and engine control console on ship maps.
-Ships need engines to move. Currently there are only thermal engines.
-Thermal engines are just a unary atmopheric machine, like a vent. They need high-pressure gas input to produce more thrust.
-
-
-1.Metaobject
-All vars needed for it to work could be set directly in map editor, so in most cases you won't have to define new in code.
-Remember to set landing_area var for sectors.
-
-2.Overmap object
-If you need custom behaviour on entering/leaving this sector, or restricting access to it, you can define your custom map object.
-Remember to put this new type into spawn_type var of metaobject.
-
-3.Shuttle console
-Remember to place one on the actual shuttle too, or it won't be able to return from sector without ship-side recall.
-Remember to set landing_type var to ship-side shuttle area type.
-shuttle_tag can be set to custom name (it shows up in console interface)
-
-5.Engines
-Actual engines could be any type of machinery, as long as it creates a ship_engine datum for itself.
-
-6.Tick map in and compile.
-Sector should appear on overmap (in random place if you didn't set mapx,mapy)
-
-
-TODO:
-shuttle console:
-	checking occupied pad or not with docking controllers
-	?landing pad size detection
-non-zlevel overmap objects
-	field generator
-		meteor fields
-			speed-based chance for a rock in the ship
-		debris fields
-			speed-based chance of
-				debirs in the ship
-				a drone
-				EMP
-		nebulaes
