* Added a proc to the map datum which returns what zlevels a nanomap capable computer should display.
* Updated the atmos control, power monitoring, crew monitoring, and camera consoles to use it.
* Changed templates to not show the map button if no map levels are available.
* Overrode it for tether to let crew monitoring computers monitor the whole station.
* Lattices no longer block all downward movement out of their turf, they only block downward falling out of their turf.
* Objects are once again pullable on catwalks (not 100% sure why they were not, but had to do with the falling code calling Move())
* Falling on top of a mob will no longer do an infinate loop of swapping places vertically.
* Don't infinately accumulate underlays!
* Ease up on the New() and Destroy(), make sure they are a top level object (loc is a turf)
* The open space darkness overlay is always the same, make it a global.
* New atom to hold a turf's decal overlays instead of the turf itself.
* Change floor_decal initialization to use it instead, and change other decal/overlay interaction procs to use it instead.
* Add floor decal initialization to master controller to do them in one fel swoop instead of nickel and diming.
* Stop area init from updating open space turfs; let the open space controller do it.
* Fix falling to check if movement actually succeeds before taking damage from falling.
* De-snowflakes how objects prevent you from falling out of their turf (catwalks and latticue)
* Improved the messaging and the way falling procs are called to make it more flexible and possible to hit things in a turf before the turf itself.
* lighting_overlay objects belong to a turf. Turfs never move. Neither should the lighting_overlay, even of an overzealous shuttle controller thinks they should.
Turbolifts, and shuttles. Please behave.
Shuttles throw everything to z1 regardless of actual shuttle destination z-level, which is silly. Secondly they literally throw it using Move which is silly. Thirdly, they do it to every atom/movable, which is unacceptable. Especially since that tries to squash lighting overlays out of the way, making weird lighting problems on shuttles.
Turbolifts qdel any 'simulated' atom/movable when they run into it, which is also stupid. This includes things like the AI Eye, which permanently deletes it. A little unfortunate, if you ask me.
