[DRAFT] As a contributor to an OSS project I want to be able to state whether I'm contributing as a volunteer, on behalf of my organization or a client

Full title: As a contributor to an OSS project I want to be able to state whether I'm contributing as a volunteer, on behalf of my organization or a client so that I can justify getting contribution time from my organization and encourage my clients to contribute

• If a user has multiple git commit email addresses configured, allow for a dropdown to select the email address from where the contribution came from (content & editorial).
  • To make this easier I suggest that this is similar to a status of a person. Eg you choose your active git commit email like a status change and this extra information is kept throughout comments, reviews etc..
