* 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.
