Changeling personal hivemind
*Creates new living mobtype: voices who are created inside of other living mobs. They communicate only with other voices in the same mob and the mob itself.

*Uses the new mobtype for changelings. Lings now have the option to absorb the "memories" of a target. The memories can ghost on their own accord or be forced out by a changeling to prevent spam or verbal abuse. After ghosting the former voice can re-enter the original body (now probably a husk).

*Adds an argument to the ghostize verb to have the ghost refer to a new mind. This was used to have voices be able to enter their own body. - Adds the option for a living mob with voices to talk to them using ":v". (This isn't in the current patch for some reason)]

*changeling powers can now have multiple verbs tied to them
*You now talk to the voices in your head with :p for personality.
*Voices now show up in the player panel. (Note that if you make the voice into a corgi with adminmagic the poor guy will have a corgi stuck inside of him)
*Voices now again count as alive. Changed that for some reason, they should of course not hear deadchat.

Adds WJohnston's rainbow esword and dual-esword sprites.  Also corrected a few bugs involving esword sprites, mainly involving the player sprite not updating when they construct dual-eswords.  It turns out that player-sprite updating is magnets, so the eventual solution was for the player to drop both swords before they're deleted.  Since dual-eswords were already created on the ground, this changes very little.
A dual-esword inherits the emagged state of the esword being attack_by'd.
WJohnston updated the sprites with a 50% longer timing.

Finally finished adding double-toy-swords, emagged double-toy-swords, and improved some of the earlier fixes.  Swords no longer have to be turned off before emagging, the player-sprite overlay will update correctly now.

- You now cannot talk to voices in your head directly. Go mad ramblings!
- Fixes two procs that had mob/dead/observer as pathname
- Added a helper proc to create voices.dm
Adding Linda.
cleared out some duplicate code in rwalls that was causing issues.  fixes issue #1070
Helper proc /proc/find_record(field, value, list/L)
It will search list/L for a /datum/data/record with fields[field] == value, and return it.

This removes a vast amount of copypasta (there's still so much left in there though). It also removes all the locate(\ref[record]) I could find, which were normal used with topic(), meaning it was susceptible to abuse.

Secbots, ed209s and turrets are now smarter with their record-checks. They now prefer to use our face-name rather than id-name. ICly, this is the bot using facial recognition. This fixes an issue where it'd try to use the name variable which could be in the format "Unknown (as their id name)" when they were disfigured, etc. causing record-lookup to fail.

Additionally, these bots will treat those without a valid record in the security database, to be treated like criminals.
Fixes "samename (as samename)" when speaking.
Fixes a typo in two visible_message() procs which gave the number 1 to people.
 * Removed unused prison shuttle code.
 * Fixed an implant/prison computer runtime. Fixes Issue #1150.
Removes TorBan.
Better alternatives are so cheap nowadays as to render it pretty useless.
Made tweaks to blob based on feedback.

Made the blob start strong but grow slower, helping stop situations where the blob is instantly caught and gets wiped out and stop the blob from being unstoppable after making 4 resource blobs.

Removed the AI quarantine laws from the blob gamemode.

People didn't like getting instantly KO'd by the blob, reduced the damage output to encourage melee engagements.

Blob overminds can see in the darkness now.
 * Removed the quarantine restriction on the mining shuttle.
The recycler machine wasn't included.
