Fixes #42

Fixes #72

Moving related content elsewhere

Allows us to use section title instead of inferring from the folder.

Also added some whitespace

Fixes #58 The aside column expanded if its content was too large.

By modernize I mean that Hugo formerly used the "section/section"
scheme, but now we can put all related section templates in one folder.

Also, more commenting!

By moving default to a page layout and posts to default, any section can
be a post. Some users were confused when they had posts that were not
named as such. No need to impose naming conventions on people.

Let's say your `.Site.Title` is "My Website". The code grabs `.Site.Title`, and then then checks to see if there's a `.Title`. When you're on the homepage, `.Title` is equivalent to `.Site.Title`, so that the browser bar will read:

> My Website | My Website

If we qualify `.Title` by confining to the `.Params` namespace, then the site title isn't duplicated:

```<title>{{ block "title" . }}{{ .Site.Title }} {{ with .Params.Title }} | {{ . }}{{ end }}{{ end }}</title>```

> My Website

But it still picks up `.Title` from posts and pages, where a content title exists in front matter:

> My Website | About Me

Fixes #70

* Parmeterize number of recent posts in index.html

* Replace .Site.Params.recent_posts_number with $.Param "recent_posts_number" in index.html

Fixes #50

Hugo's `.Summary` did not behave as I expected it to, not stripping out
HTML, so I removed the anchor block from around the posts and moved the
links to the image, title and a read more button.
