Week 10/11: Staged WHATWG patches for HTML5.1 & Microdata

Hi again,

This week the following WHATWG patches up to and inc commit 7759 [1] have
been cherry-picked into the W3C HTML specification (master branch) for
HTML5.1. This takes us to WHATWG patches up to 17th March 2013 (i.e. we are
up-to-date).

You can see the actually committed patches here:
https://github.com/w3c/html/commits/master (18th March).

of legacycaller from HTMLPropertiesCollection.
