start auditing contributors to check for relicensing

[mr-c]

I'm checking to see which contributors have not agreed to the retroactive MIT licensing request, and documenting the evidence for those who did.

There are 631 unique author name/email addresses in the git history, so help is appreciated!

Please comment in this PR if you are working on this, to avoid duplication; state the alphabet letter you are working on, or some other indication

My process

1. Browse the author list and pick up where I left off: git log --pretty="%aN <%aE>" | sort -u | less
2. Put an entry in the .mailmap even if there is only one variant for that contributor
3. Add other variants to the .mailmap as they are found. Use the extended version (source name and email address) if the email address is generic, like <user@user-MacBook-Air.local>
4. Check git log for the most recent commit, and look it up at https://github.com/galaxyproject/galaxy/commit/${HASH} to get the GitHub username. Clicking on the username should bring up a list of all their contributions to this repo: https://github.com/galaxyproject/galaxy/commits?author=mr-c
5. If there is a post 2021-04-07 commit, click through to find the PR and ensure the the MIT retroactive license grant box was checked. Add the contributor's GitHub username, primary email address, and that URL to the first table in doc/relicensing/status.txt
6. If there isn't easy evidence for MIT re-licensing, then add their details to the second table in doc/relicensing/status.txt

Note: some contributors might be left out of the mailmap for privacy reasons

• IMPORTANT remove .mailmap before merging

I'm going to pause for now, I'll resume work on the As later

@mr-c I've started from Z upwards, just pushed a commit, hopefully no conflicts with your work.

Thank you @nsoranzo ; any updates to doc/relicensing/status.txt, or are you just doing a cleanup of the contributors list (also still helpful!)

I am focusing on the mailmap currently.

@natefoo and I have been in contact with @Slugger70's family regarding the relicensing of his contributions. We requested the agreement of someone who inherited these contributions, included a copy of the license and background information on why we were requesting it, and have an emailed confirmation from his son:

Yes, I agree that my father, Simon Gladman's historical contributions can be relicensed under MIT
