Rewrites shield handling to be less hardcoded.
Shields now take into account the damage source and direction when blocking.
Riot shields no longer block most bullets, but are better at blocking melee and thrown items than they were previously.
Energy shields block projectiles with a similar probability as they did before, and block melee and thrown as well as riot shields do.
Shields no longer block from directly behind the player.
Weapons now only block melee attacks.
Cool effects when blocking with an energy shield or energy sword (including holoswords).
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.
Removed defines/obj/toy.dm and moved the defines down to objects/items/toys.dm
Moved a big chunk of defines out of defines/obj/weapon.dm and into their respective .dm files.
