Sm/sandboxes-in-list

What does this PR do?

well, this started off as "make sandboxes a section within org:list" (we can do that more reliably now thanks to Steve's PR for identifying them)

also, while I was in here, I realized how ugly that table is. So

1. remove all the extra ASCII characters.
2. default markers (U) and (D) don't mean anything and don't even align with flags anymore. Those are now emojis and there's a legend at the bottom of the table. If you've got better emojideas, holler.
3. One table so the columns align
4. Type field (DevHub, Sandbox, Scratch Org, ?) [the original WI]
5. colors by type, orgs are grouped by those types
6. aliases are at the top of their section instead of the bottom
7. instanceUrl appears when --verbose for non-scratch orgs, too
8. long datestamp for createdDate is now just yyyy-mm-dd to match ExpirationDate
9. Column headers are title case instead of UPPERCASE

No JSON should be harmed in the making of this PR

What issues does this PR fix or reference?
