Adding a Code of Conduct to MacPorts

[Jackson Isaac]

Lately, I have seen open source projects have started adopting Code of
Conduct. [1], [2]

I think it is a great step to keep the open source community healthy
and welcoming to everyone.

I would like to know what other developers think about this. Also, who
would be the decision makers (PortMgrs?)
