Apply AI Controller Admin Verb (#89375)

## About The Pull Request

Melbert asked me to make this and I thought it'd be relatively easy and
plausibly useful so I did.

This PR adds a feature to the VV menu for mobs which allows you to apply
and configure an AI controller from a list of templates.
It's not as versatile as coding one would be, but it should be able to
accomodate a lot of generic scenarios.

Some examples of basic stuff you can set it up to do:
- Give Ian a machine gun he will fire at nearby people while staying
within a specified min/max range.
- Have Poly fire brimstone beams on cooldown at whoever is nearby
(although she won't bother trying to line up cardinally).
- Assign a gorilla to be someone's personal bodyguard which will follow
them around and attack anyone who hurts them.

I have also made an executive decision to remove the restriction that
basic ai controllers can only be placed on basic mobs.
We've removed _most_ non-basic simple mobs from the game, and also have
more recently updated most AI behaviours to work agnostically of whether
they are assigned to a basic mob or not... which means that they'll
largely work on carbons.

Coincidentally, this feature makes sure to ask if you want an AI
controller to remain active on a mob which already has a client.
Assigning an active AI controller to a live player which forces their
character to automatically attempt to run away from whoever the last
person to attack them was is ~~not recommended behaviour because it's
largely untested~~ highly recommended behaviour because I think it's
very funny (makes it very hard to play though).

I'm gonna do another PR some time which cleans up `random_speech` so
it's configurable and then let you slap that on whoever as well.

## Why It's Good For The Game

Enables a greater level of admin abuse.
