Consider expanding Code of Conduct?

[Bill Hunt]

You all have a great Code of Conduct policy so far! But it could be even better if you expand the language of inclusion beyond the "standard legal requirements" - have a look at 18F's for some really great additions:

In particular,

Negative or offensive remarks based on the protected classes as listed in the GSA Anti-harassment Policy of race, religion, color, sex (with or without sexual conduct and including pregnancy and sexual orientation involving transgender status/gender identity, and sex-stereotyping), national origin, age, disability (physical or mental), genetic information, sexual orientation, gender identity, parental status, marital status, and political affiliation as well as gender expression, mental illness, socioeconomic status or background, neuro(a)typicality, physical appearance, body size, or clothing. Consider that calling attention to differences can feel alienating.

That looks good to me. I'll make a pull request with the change :)
