Pagination only for posts

[paapereira]

I asked for pagination a little while ago, and I got it :)
But it left me with some broken features in my site. Basically the 'posts' link works as expected with pagination, but the 'categories' link for example stopped working.
Before the 'categories' link listed the categories of posts and with the commit it started showing the posts as the 'posts' link.
To 'fix it' I rolled back the hello-friend-ng/layouts/_default/list.html and added a copy of list.html with the pagination fix to hello-friend-ng/layouts/posts/.

Probably not the best solution, but it worked for me.

If you can see if it is fixable I could continue to pull your fixes :)
