Adds Radioactive Microlaser

Adds the radioactive microlaser, a device disguised as a health analyzer
used to irradiate people, as a traitor item. It costs 4 telecrystals to
purchase, and is fairly powerful in clever hands.

The strength of the radiation is determined by the 'intensity' setting,
while the delay between the scan and the irradiation kicking in is
determined by the wavelength.

Each scan will cause the microlaser to have a brief cooldown period.
Higher intensity will increase the cooldown, while higher wavelength
will decrease it.

Wavelength is also slightly increased by the intensity as well.
Adds sprites to ling armor & shields.

Stops players from seeing the coder conspiracy
Balancing

Tweaks the cooldown numbers, as well as the wavelength calculations.

Anti-toxin, hyronalin, and arithrazine all reduce the effects of the
radiation now.
Fixes scan message

Now it uses the right color and punctuation

Removes wonky luminosity check from soil plots that was causing problems.  Was not present in real hydro trays.
Puts the irrigation check back to anchored==2 like it's supposed to be.  Oops.
Comments the anchored variable in a few places so people don't make the same mistake.
Fixes some issues with mechs getting deleted
Mechs delete correctly, and delete their special looping iterator datums just for good measure. Also now sanity check them because now they can be null.

Fixes #4067 hopefully. This issue is impossible to repro alone and even then it's one-in-a-million, but I've removed a bunch of spawn()s that only served to create a window one can jump inside between the mech running the deletion proc and actually running Destroy() and setting loc = null. I've also added two safeguards to make sure it doesn't happen in the future. Can't enter a deleted mech and getting deleted kicks anyone inside out just to be sure.

Removed the super pointless obj/mecha/proc/destroy(). Even when this was written, it should have just been in Del()!
