atom output for threads with multiple posts is unreadable

our feed template just concatenates all of the post sources, without any way to distinguish them. not to mention the multiple base tags, which are all the same (and even if they were different, that won’t work).

<content type="html" xml:base="{{ SETTINGS.external_base_url }}">
{% for post in thread.posts -%}
{#- fluent-reader needs html base tag, not xml:base (yang991178/fluent-reader#692) -#}
&lt;base href="{{ SETTINGS.external_base_url }}"&gt;
{{ post.original_html }}
{%- endfor %}
</content>
