(#1177) Add a new SubmissionModerationFlair class

[PythonCoderAS]

Fix for issue #1177

Still needs some integration tests but I do not have an account that I can use user/pass with that also has a subreddit so I am unable to run any integration tests.

Furthermore, when trying to update the changelog, it causes a whole bunch of issues so I had to go change entries from PRAW5 and earlier.

Regarding integration tests, I create a few test subreddits for my test accounts to be a moderator of.

@bboe can you make my alt mod in order for me to generate the tests?

[PythonCoderAS]

It's so exciting when coveralls fails. These tests need to be re-run

You should be able to create your own subreddit(s) and make your alt(s) mod on them.

If you rebase you can force push thus triggering a new build yourself. You can also do a similar trick by slightly modifying your commit message via git commit --amend to result in a new commit and then force-push to your branch.

Once I get onto a PC I’ll merge fix that.

I unfortunately won't have the time to dig into this PR today. Possibly tomorrow, but it might not be until next weekend for me.
