SkyratBot 30530f2c96 [MIRROR] AI actions won't unassign each other's movement targets & Mice stop being scared of people if fed cheese [MDB IGNORE] (#18268) 
AI actions won't unassign each other's movement targets & Mice stop being scared of people if fed cheese  (#72130)

## About The Pull Request

Fixes #72116 
I've had a persistent issue with basic mob actions reporting this error
and think I finally cracked it
When replanning with `AI_BEHAVIOR_CAN_PLAN_DURING_EXECUTION` it can run
`Setup` on one action leading to the plan changing, meaning that it runs
`finishCommand` to cancel all other existing commands
If you triggered a replan by setting up a movement action in the middle
of another movement action, cancelling the existing action would remove
the target already set by the current one.
We want actions to be able to remove _their own_ movement target but not
if it has been changed by something else in the intervening time.

I fixed this by passing a source every time you set a movement target
and adding a proc which only clears it if you are the source... but this
feels kind of ugly. I couldn't think of anything but if you have a
better idea let me know.

Also while I was doing this I turned it into a feature because I'm
crazy.
If you feed a mouse cheese by hand it will stop being scared of humans
and so will any other mice it attracts from eating more cheese. This is
mostly because I think industrial mouse farming to pass cargo bounties
is funny.
Mice controlled by a Regal Rat lose this behaviour and forget any past
loyalties they may have had.

Oh also I removed a block about cancelling if you have another target
from the "hunt" behaviour, everywhere using this already achieves that
simply by ordering the actions in expected priority order and it was
messing with how I expected mice to work.
Now if they happen to stop by some cheese they will correctly stop
fleeing in order to eat it before continuing to run away.

## Why It's Good For The Game

Fixes a bug I kept running into.
Makes it possible to set up a mouse farm without them screaming
constantly.
Lets people more easily domesticate mice to support Ratatouille
gameplay.

## Changelog

🆑
add: Mice who are fed cheese by hand will accept humans as friends, at
least until reminded otherwise by their rightful lord.
fix: Fixed a runtime preventing mice from acting correctly when trying
to flee and also eat cheese at the same time.
