Configure entries layout list or grid (mmistakes#2616)

* Configure entries layout `list` or `grid`

This allows to use grid layout on `page.entries_layout` on the home layout.

Included a break since when using grid the post images are too close to the horizontal line bellow `posts` text.

There's a entries div now surrounding the posts since the first row of the grid was having a slight padding on the left. The home now behaves like posts/categories/tags pages with grid but including the paginator.

For best results on desktop use `classes: wide` and `paginate: 4` on `_config.yml` (or multiples of 4 if you want more rows)

* Fix indent

* Archive subtitle leaves space on the bottom

* Now space is added through style
