Proposal: .saorc file

[egoist]

A global config file to reuse SAO's CLI options, like --registry --npm-client, and potentially in the future, --github-token etc.

Even setting these options in saofile.js or a seperate per-generator config file would be 👌

I'm currently aliasing sao in zsh to pass in opts every time its used instead, which is pretty messy
