Collate_posts helper. Collated posts by year and month.
Usage:
1) assign the 'posts_collate' variable to a valid array of posts.
2) include JB/posts_collate
example:
{% assign posts_collate = site.posts %}
{% include JB/posts_collate %}
Ordering:
Posts are displayed in reverse chronological order.
For normal chronological order:
1) Change the for loop to this:
=> 'for post in site.posts reversed'
2) Next make sure to change 'post.previous.date' to:
=> 'post.next.date'
