Partial port from vgstation.
Notable differences:
handle_regular_hud_updates() is called anytime view is reset, instead of
just from the cancel camera verb. check_eye() now returns the vision
flags to be set on the viewer. Moved cameraFollow to silicon. Camera
consoles now call reset_view explicitly when they want to change a mob's
view, instead of leaving it as a side effect of check_eye()
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.
