First big chunk of the refactor

mid-refactor of `take_overall_damage`

Fully refactors the (?:take|heal)_(?:overall|organ)_damage procs

Allows the dead to examine

Removes the `blinded` var

Refactor cyborg components so vision loss is instant

Robot life/death updates instantly

Adds instant updates for damage overlays and HUD icons for humans

Final reconciliation with the species refactor

Adds a stat debugging system and debugging logs

Also fixes instant death on species change

"Debugging logs" are used for stuff an admin wouldn't care about but
someone debugging would

I used it to fix people dying instantly when changing species due to
temporary deletion of the brain

Fox's requests

Adds a more careful updating system to our reagents system
