* Add head-additions partial

The way relURL was used meant that one needed to preface the custom_css
entries with a slash, or the href would be incorrectly set to
subdircss/mycss.css rather than subdir/css/mycss.css, in the case of
a baseURL in a subdir.

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
