* PEP 8016: more tweaks based on discussion
* Removed the requirement that council members have to be core team
members; added the requirement that non-core-team council candidates
need to be nominated by a core team member. Rationale: Steve Dower
is worried that we may have a shortage of core team members who are
willing to serve on the council. I'm not worried myself, but I like
Steve and don't want him to worry; this is an easy way to help with
that. Requiring a core team member nomination should be harmless,
since any candidate that can't get a nomination is certainly not
going to win a vote, and it lets us filter out random jokers early.
* Added some language to emphasize that emeritus core team members
will still be listed on the website and their past contributions
will continue to be recorded.
* Changed the vote tie-breaker from "seniority as a core team member"
to "mutual agreement or random chance". Victor pointed out that
seniority is not always known or unique, and anyway this doesn't
make much sense if we're allowing non-core-team member candidates.
The goal was always just to have some unambiguous resolution that
doesn't require voting again, and this seems like a simpler and more
reliable option.
* Clarified that in the never-going-to-happen edge case where a core
team member misbehaves so badly that the project has to kick them
out AND that core team member is on the council, then they're also
removed from the council.
* Added link to the second discussion thread.
* Made a few small wording tweaks and fixed some ReST formatting.
* PEP 8016: fix the definition of "Python committer" to match reality
* Rephrase the emeritus text again, to hopefully be even more clear
* One more wording tweak
* s/emeritus/inactive/, and remove the [TBD]
