Posts without an explicit title render the date as the post header in
lists of posts (like on the blog index and tag pages). This updates
localdate.js to properly adjust those dates, too.
this adds a helper script to rewrite all time elements with a proper
datetime attribute into the users locale via the browser
navigator.language.
collection, collection-post and chorus-collection-post templates now
include this script
