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.
Protolathe and CI build procs moved to them from RD console.
Protolathe and CI now have a build queue. Designs take varying time to
build.
P and CI material storage is now a list instead of a set of vars.
origin_tech is now a list.
All sheets now contain exactly 2000 units of matter.
In design datum, chemicals and materials are two separate lists.
Designs are now sorted. The method is kinda hacky but flexible. They
have a var, sort_string. Designs are sorted alphabetically using it.
Circuits how show whether they build a machine or a computer in CI menu.
Adds item construction, for now protolathe is used.
