Make the blob nucleus more visible

[Marquesas]

My issue was that I read into it that you'd like all organs to be done this way (lipids, ribosomes, and so on), which is sort of a heavy deal as it would replace an icon with several overlays, and blob is heavy enough as it is. I gotta note that the idea itself is not bad, it lifts all restrictions, but for everything I wouldn't risk it. There's a way we can do it for the nucleus though.
