#167 Dummy view for importing committees and countries via admin panel.

Adjusted the admin view to load csv files. Things still to do: write a unit test, and make it functional (it currently returns an index error because the csv reader returns an empty list).
Since you are no longer modifying this block of the template, you can just call the parent template's block. I believe this could be reduced down to:
```
{% block object-tools %}
    {{ block.super }}
    <form>
      ...
    </form>
{% endblock %}
```
Technically, we are skipping the `has_add_permission` check, but I think that's okay. We can assume that if the user can access the admin panel, they can add committees.
