Before this commit, Hugo used `html/template` for all Go templates. While this is a fine choice for HTML and maybe also RSS feeds, it is painful for plain text formats such as CSV, JSON etc. This commit fixes that by using the `IsPlainText` attribute on the output format to decide what to use. A couple of notes: * The above requires a nonambiguous template name to type mapping. I.e. `/layouts/_default/list.json` will only work if there is only one JSON output format, `/layouts/_default/list.mytype.json` will always work. * Ambiguous types will fall back to HTML. * Partials inherits the text vs HTML identificator of the container template. This also means that plain text templates can only include plain text partials. * Shortcode templates are, by definition, currently HTML templates only. Fixes #3221
