``/mob/dead/observer`` -> ``/mob/observer/dead``
``/mob/eye`` -> ``/mob/observer/eye``
Reason being that they are similar in that they both don't interact with
the world in any way. Some procs were shared, some checks as well, and
it overall makes more sense this way. Plus, there were no ``/mob/dead``
mobs.
This means that instead of the base turf being defined by the z-level, it's now defined by area and defaulted by z-level.
Updates all "shuttle" and "solar" areas to have a base_turf of space.
Updates docking arms 1, 2, and 3 on the main asteroid level to have a base_turf of space.
Other z-levels may still need updating.
This change means that all actions which destroy or dismantle a tile - for example bombs, a singularity, a shuttle leaving, or deconstruction - now leave these new areas as space not asteroid. Future mapping efforts may need to take this into account.
Created a global list to track base turfs for explosions/shuttle moves.
Remaps the asteroid to be a moonlet. Tidies up some references to 'asteroid', removes moonbase from the accessible z level list.
