Twenty Thirteen: add support for quote structured post format

[obenland]

With the switch to supporting structured post formats, Twenty Thirteen no longer gets to enjoy the heavenly cushions of post_format_compat().

[obenland]

I took inspiration for the quotes markup from ​this article.

Might be good to split out each post format into a new ticket. So quote, link, etc. (Instead of all here in one ticket.)

[lancewillett]

Discussing in today's IRC office hours, we are going to push the markup improvements to core, into the postpost_formats_compat() function -- and trim the Twenty Thirteen patch here to just CSS support.

[lancewillett]

See #23347 for the updated quote post format markup; ​http://core.trac.wordpress.org/attachment/ticket/23347/23347.10.diff is the relevant patch.

In 23802:

Twenty Thirteen: add styles for default core output for structured quote post format. Depends on #23347 for the improved markup for quote post formats. Props obenland, see #23852.

[lancewillett]

In 23803:

Twenty Thirteen: explicitly declare 'link' and 'video' as the only (current) structured post formats in Twenty Thirteen. See #23852 #23619 #23864 and #23620.

Looks like we still need styling for the figcaption — since it replaces cite.

.3 patch is refreshed after feedback from Obenland.

[obenland]

Can we use .quote-caption instead of blockquote + figcaption, .quote-caption figcaption, and .entry-content figcaption ? I think it's simpler.

I'm sorry I didn't point that out before, I thought you wanted to globally style the figcaption element.

Yep, makes sense now.

Thanks for the updated patch, testing again now with both structured and older post-content quotes.

[obenland]

Turns out we can remove a bunch of stuff now with the new markup.

Right, but I think we should also support fallbacks to "normal" blockquotes and cites if people enter them into the post content.

Think of someone upgrading to 3.6 and Twenty Thirteen but with a bunch of older Quote post format posts.

In 23829:

Twenty Thirteen: refresh Quote post format styles based on new default markup, see r23822. Props obenland, fixes #23852.
