Fix RSS block example in documentation (#1210 )

This commit fixes a bug in the documentation for the feeds page which
shows how to use the RSS block to enable feed autodiscovery.

The bug used an em space character instead of a space in one part of the
code snippet. If a user were to copy the code snippet into their code as
directed, the Zola build would fail with a parse error. The em space
appears identical to a regular space in monospaced fonts, making the
error seem mysterious or incorrect.

I believe the em space was used in order to prevent the shortcode from
rendering, as the code snippet is just meant to show what the shortcode
looks like. However, it is possible to escape the shortcode so that it
renders correctly without causing confusion for the user who expects to
be able to copy and paste it.

This commit replaces the em space in both code snippets with regular
spaces and escapes the shortcodes.

If the site config.toml file sets generate_feed = true, then Zola will generate a feed file for the site, named according to the feed_filename setting in config.toml, which defaults to atom.xml. Given the feed filename atom.xml, the generated file will live at base_url/atom.xml, based upon the atom.xml file in the templates directory, or the built-in Atom template.

feed_filename can be set to any value, but built-in templates are provided for atom.xml (in the preferred Atom 1.0 format), and rss.xml (in the RSS 2.0 format). If you choose a different filename (e.g. feed.xml), you will need to provide a template yourself.

Only pages with a date will be available.

The feed template gets five variables:

config: the site config
feed_url: the full url to that specific feed
last_updated: the most recent updated or date field of any post
pages: see page variables for a detailed description of what this contains
lang: the language code that applies to all of the pages in the feed, if the site is multilingual, or config.default_language if it is not

Feeds for taxonomy terms get two more variables, using types from the taxonomies templates:

taxonomy: of type TaxonomyConfig
term: of type TaxonomyTerm, but without term.pages (use pages instead)

You can also enable separate feeds for each section by setting the generate_feed variable to true in the respective section's front matter. Section feeds will use the same template as indicated in the config.toml file. Section feeds, in addition to the five feed template variables, get the section variable from the section template.

Enable feed autodiscovery allows feed readers and browsers to notify user about a RSS or Atom feed available on your web site. So it is easier for user to subscribe. As an example this is how it looks like using Firefox Livemarks addon.

You can enable posts autodiscovery modifying your blog base.html template adding the following code in between the <head> tags.

{% block rss %}
  <link rel="alternate" type="application/rss+xml" title="RSS" href="{{/* get_url(path="rss.xml", trailing_slash=false) */}}">
{% endblock %}

You can as well use an Atom feed using type="application/atom+xml" and path="atom.xml".

All pages on your site will refer to your post feed.

In order to enable the tag feeds as well, you can overload the block rss using the following code in your tags/single.html template.

{% block rss %}
  {% set rss_path = "tags/" ~ term.name ~ "/rss.xml" %}
  <link rel="alternate" type="application/rss+xml" title="RSS" href="{{/* get_url(path=rss_path, trailing_slash=false) */}}">
{% endblock rss %}

Each tag page will refer to it's dedicated feed.
