[theme-reviewers] Things to Consider for Theme Upload Checker

[Otto]

Oh, I also wanted to add that the reason that particular one (
automatic_feed_links() ) is marked "REQUIRED" is because it produces a
deprecated function notice.

And the theme review guideline states:
"Themes are required not to have any notices, warnings, errors; or use
of deprecated functions."

So all the deprecated functions produce that REQUIRED message. It's a
fairly long list of 103 function calls it's checking for there.
