Blood Refactor (#6220)

* commit for branch swap * branch swap again * BLEED * trying to clear up compile errors * i killed everything when i tested this... * restorealltheblood * I REMOVED A THING * well some progress * stop bleeding * got to swap branches again. * grr * damn bloodcolors * Squash everything * color....colourrrrrrr * color....colourrrrrrr * well now that updated the branch... * Changes * Some tweaks..before i upload something major * COLOR NOT COLOUR...COLOR YES I KNOW NOT EVERYONE SPELLS IT LIKE THAT BUT MY GOD * Foot print shit.. blood coloring is going to be PAIN * trying to handle some colors..maybe. * blood colorsing sucks..di i mention this? * commenting cod malfunctions. * Changes * lets try this * Its too late at night. * blargh * woops * almost works... * progress.. * Branch swap * figured out the overlay issue.... * BRANCH SWAP * BLARGH * fixed merged conflicts..expect something to be horribly wrong. * bunch of changes * Major Fixes - Moved blood_state and bloodiness var definitions to /obj/effect/decal/cleanable/blood as well as /cleanable/Crossed(), in order to make blood color work properly. - These were not used by any other decal, so it was pointless. - Tweaked human/add_blood so that hand_blood_color uses the correct value now. - Corrected gibs having the wrong basecolor. - Tracks of different blood colors will no longer combine weirdly, and will instead form seperate overlays. - This also fixes all of the issues with tracks in general and not updating correctly. - Fixed transfering blood in add_fingerprint; the old detective code didn't use the new format for add_blood(). - Fixed xenomorphs causing runtimes in makeTrail(), and gave them their own trails. Sprites should probably be brightened later. - Fixed mobs occasionally randomly having their blood_DNA list reset. * may have accidently removed shit. * Mrowl * stiff water is not bleeding lowered trail making threshold * tweaks then conflcits * weee * indent * some tweaks * somefox tweaks. * derp * why won't they bleed!? * BLEED DAMMIT * Flattist comments and removes simple animale blood volume Cause i cannot get it to work right. * PRAISE FLATTIST * Simple animals have a blood volume now Bug with trail fixed. * changes * thanksmrowlmrowl * exotice blood trails * makesure is an exotic bleeder has a bleed rate first... * FoxBoxTweakSox * BoxVoxSoXFox * ONE MORE THING * animalsbleedreds * Buh? BUGH! * thisismescreaming * removing note needed thing * Color changes but the rabbit hole continues. * This is not pretty.... * wot * IT WORKS DAMMIT * colors. * germaphobic commit.. * we have to use the old system * nothing to see here * doubleprocarady * try to fix mulebots * mulebot fixed * DONE
