Allows eyes to track eye-dependent disabilities when removed from the mob.
Farwas and Wolpins are now incurably colourblind (non-genetics based), so going lesser-form and back won't wipe your colourblindness.
Eyes being straight-up deleted (as per how set_species() handles setting up the organs required for the species we're changing to) no longer wipes colourblindness.
Now with more helper procs, less unnecessary commenting, random changes and other cleanliness-related tweaks.
For Vulpkanin and Tajara, it gives them their species-specific
colourblindness but their excellent darksight, too. Otherwise it gives
noir vision.
You can choose this disability at character creation. It is off by
default. You can turn it off via genetics and mutadone.
Fixes Cling Transform&Lesser/Greater form & Darksight bugs
Transforming to an identity will now, with 100% reliability, give you
the exact appearance as that ability bar the body_accessory and the
secondary hair/facial hair colours. Same thing with going from lesser
form to an identity that was not the one you lesser formed with.
Fixes the darksight bug from the last commit, happened 'cause typo.
Woops.
Eye Transplantation Applies Eye-dependent Genes
Transplanting colourblind Vulpkanin/Tajara eyes into a Human gives the Human
the dark_view and unique colourblindness of said Vulpkanin eyes.
Removing colourblind eyes will take the disability with it, meaning the
person will have colour vision/low darksight.
