#352: move english content to content.en

Prior to this commit, the partial for determining a page title used the
`Title` property of a page, if present, or humanized and titleized the
file name if not.

It did not use the `LinkTitle` property at all (defined in the
[front matter][01]). According to the [menu documentation][02]:

> The following order is used to determine an Identifier:
>
> `.Name > .LinkTitle > .Title`
>
> This means that `.Title` will be used unless `.LinkTitle is present,
> etc.

Similar, the documentation for [menu entry variables][03] states:

> The `name` key, if set for the menu entry, sets this value. If that
> key is not set, and if the menu entry is set in a page front-matter,
> this value defaults to the page's `.LinkTitle`.

Together, these imply that if `.LinkTitle` is specified, it should be
preferred over `.Title` for the generated nav menu.
