More surgery tweaks and fixes (#18823)

* Surgery Defines

Adds some defines to surgery to make it easier to track how 'open' someone is instead of magical numbers.

* Make frankensurgery less punishing

Makes frankensurgery less painful.

Resleeving is a thing and is MUCH easier to do.

Having brain surgery apply a permanent debuff to people just means that the 'ideal' thing is to always resleeve/clone. This gets rid of the debuff.

* Setting vital in a few places

* Makes infected wounds not kill in stomachs

Wounds still accumulate in stomachs, BUT the germ level of the external organ won't increase while being digested, meaning you won't get massive infections while doing a long-digestion scene.

It was done here instead of in handle_germ_effects() so you can't just eat someone with major infections and act as a statis stomach.

* Internal bleeding tweaks

Makes internal bleeding slower if you have the IB cure (myelamine)
Makes internal bleeding not get worse if you have the dermal equivalents of bicard+inaprovaline

* Update neck.dm

* Some more aggressive reform healing

Makes reform healing do some more healing to bring them back. Instead of healing just 6, heals a flat 25 now of brute, fire, clone, and toxins.

It then sees if you're 'below revival point' and if so, it gives you a much stronger heal to ENSURE you are brought back.

* forgor to check this in the .dmi

This is what happens when you have minitest selected and have your .dme ignored by default!

* Update blood.dm

* this comment is no longer relevent

We have LVADs now!

* Makes tourettes not trigger more if you have slow pulse

This was presumably meant to increase your chance of a tic if you have a higher pulse, not if you have a slower/more calm pulse.

* More edits

* Update generic.dm
