Feature request: include markdown in templates

[ivanistheone]

Would it be possible to create an includemd template tag similar to the django include tag which is used to include fragments? For example, in a regular django template, I'd like to pull in the text content from somefile.md as follows:

<div class="row">
{% includemd "somefile.md" %}
</div>

If you think this would be possible, I'll look into it and open a pull request.
