Visible Not Gate

[Potato-Man1234]

Description of the feature

What it says on the tin, a visible version of the not gate, to reduce some confusion on outputs

Why should this be implemented

see above

Additional information

Should be in the HMW logic gates and the xor should get an invisible version

I've actually been working on this - a single-input inverted gate is treated as a NOT, since NAND, NOR and XNOR all behave identically to one in that case.
