Added the Packaging on the Web specification per the CfC to do so in
<http://lists.w3.org/Archives/Public/public-webapps/2014AprJun/0445.html>.
Added the Selection API plus a few editiorial fixes.
Remove "HTML Editing API" since the group agreed to just focus on the Selection API (at least initially).
