[whatwg] Datalist missing from XHTML5B module definition

[Matthew Raymond]

If you look here:

http://www.whatwg.org/specs/web-forms/current-work/#xhtml-module-def

...You will notice that the <datalist> element is not included in the 
definition of the XHTML5B module. Also, in the same section, the 
<select> element doe not have a |list| or |data| attribute.  Please 
correct the draft to properly reflect the new element and attributes.
