## About The Pull Request
Adds a new staff for the wizard that shoots shrink rays. Also a
corresponding wand that comes with the wand belt. Shrinking is a
mechanic already implemented by abductors, but it's not often used
because it doesn't fit their kit super well. That's a huge shame because
shrinking stuff/people is really funny. And you know where funny stuff
fits well? The wizard kit.
OH YEAH and being shrunken now gives you the squash component so you can
be squashed as though you were a roach, though this only deals 10 damage
instead of gibbing you

tiny wand

exhausted wand turns back to a big wand sprite :)

## Why It's Good For The Game
Shrinking stuff is funny, plus it gives the wizard something new to do
besides polymorphing everyone or turning everybody to stone or ei
nathing people.

Adds set_density()
Fixes one instance of a duplicate density assignment on an object.
Comments two hacky usages of density which will have to forgo using the setter for now.
Lets us append code to the event of density changing.
Pretty sure this is leading up to some multitile object thing -Lemon

* Opacity refactor (#52881)
Moves all opacity var manipulation to a proc which sends a signal.
light_blocker element for movable opaque atoms made, which tracks its movement and updates the affected turfs for proper lighting updates.
has_opaque_atom boolean replaced by the opacity_sources lazylist to keep track of the sources, and a directional_opacity which serves a similar function but also allows for future expansion with on-border opaque objects (not yet implemented).
Some opacity-related sight procs optimized as a result of this.
Some variables moved to the object's definition.
A define or two added into the mix for clarity.
Some code cleaning, like turning booleans into their defines.
One file renamed for clarity.
Changelog
cl
balance: Mechs no longer block sight. It's a non-trivial cost for the lighting system with little to no gain.

About The Pull Request
It adds a shrink ray that has 5 shots, can be recharged, has unique (coder)sprites, and has a cool sound
Shoot a thing with the shrink ray to make it small. Anything can be shrunk except floors
Shrunken things grow back after a couple seconds, might adjust this
Small things will not block vision and can be walked over (this includes walls)
Small people won't fit into their clothes and will drop all their stuff (or rather, their stuff will drop off of them). They also can't move very fast, and take 2x damage while shrunk.

It's really goddamn cool
Changelog
cl PKPenguin321, Fury McFlurry
add: A shrink ray for abductors that they can buy at their console for 2 experiment points. Anything can be shrunken, and shrunken things can be walked over/seen past (for example, you can shrink a wall and then walk around it). If a human is shrunk, they will drop all of their belongings, move slower, and take 2x damage.
imageadd: Shrink ray sprites by Fury McFlurry. Thank you!
/cl
I intend to add it as a thing abductors can purchase but am putting it up now for code review and if anybody has any other ideas on good thematically fitting places to put it.
