Brain Traumas (#31727)

* Reworks Brain Damage

* mechanics

* rebalancing

* hulks in wheelchairs

* yup

* bugsquash

* Adds narcolepsy, phobias and agnosia. Not guaranteed 100% bug-free yet, testmerge at your own risk.

* lizard phobia

* Did you know there's a skeleton inside of you RIGHT NOW?

* Fixes for the new stuff

* The issue with those is that in most rounds you won't see them

I'll keep them available so they can be added manually, for example by events and such

* Goof reviews

* Brainloss is based off brain organ integrity

removes brainloss var

* Replaces some getorganslot with defines

* eyes

* put the traumas in the brainnnn

* text

* args

* Adds godwoken, puts split personality in severe, adds brainwashing

* Bluespace prophet special trauma (untested)

* Some minor stuff

* Monophobia, and tweaks

* More fixes

* fix

* a

* new tail

* Discoordination and Muscle Weakness

* thanks for the review!

* [B]oneless

* agnosia fix

* .

* go away agnosia

* pretend it didn't happen

* Shitcode-free-er

* bitwisdom

* psychotic brawling

* i guess this might be important

* latest reviews

* .

* conflict-free

* addresses it

* surgery fix

* a masterpiece

* fix

* fix again

* config

* damage formula reworked

* who needs to test anyway

* fixes some bugs

* fix 2

* proper spookin

* bluespace prophet fixes and improvements

* no bible healing

* .

* normalizes monophobia chances
