Title: Add site.posts_archive for Issue #80

Now, in addition to `site.posts` the Posts extension provides a
`site.posts_archive` method returning Archive::Extensions::Posts:Archive
To get an array of all the posts for August of 2012, call
`site.posts_archive.posts[2012][08]` which returns an array of posts
sorted by date.
