* Two organ bugfixes
First, allows FBPs with synthetic brains (posis and drones) to actually die from massive brain damage. Before, although the damage would still affect them, robotic vital organs taking 60+ damage would never actually kill the owner.
Second, stops the zombie organs bug from popping up in normal play. You were able to repair all the damage on an organ, but not the ORGAN_DEAD status, leading to "dead" organs that still functioned (and that you could never die from them taking damage). Now, repairing the damage surgically will remove that.
* Repair for dead undamaged organs too
-Fixes flat white background capitalization error.
-Re-enables tunnel plating and reinforced floor. (turf versions now up to date)
-Adds darker plating, ribbed techmaint tiles, and flat middle grey.
-Tweaks their cycle order to cycle flats by shade, and then tiles by shade.
- The deletion of the circuit board without clearing the circuit variable caused it to be hard-deled by SSgarbage after several minutes. After that point, use of RPD or attempt to deconstruct would runtime.
- Pipes have been deleting themselves in update_icons() This is crazy, don't do it.
- The only real reason they have been doing this is to prevent pipes from disconnected on both ends because no icon states existed for it. So I just made icon states.
-Makes leg icon cache code little more robust in the hunt of the dreaded bugson dismemberment crash.
-The old leg layer direction caching code was pretty slippery to grasp and basically the only thing left separating it from the other well behaving limbs at this point.
-The cache blending runs each limb on its own so there is no practical need to (con)fuse the left and right legs together like that.
-Not entirely sure how exactly the old code did the stuff(itjustworks.ogg), but the new one goes straight to the point, picking the side of the processing limb, grabbing its overlay appropriate direction icons onto one temp, blending the overlay set onto base before grabbing the underlay appropriate dir by itself into a separate(free of the overlay temp shenanigans) and underlay blending it onto the base.
