Added new hook "before_suit_styles"

[brunocascio]

Hi guys!
I added another hook for template. Is this possible?
My project have other css framework, but i need load before bootstrap because some styles are broken.

Use example:

{% block before_suit_styles %}
  <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/semantic-ui/2.0.4/components/icon.min.css"/>
  <link rel="stylesheet" type="text/css" href="{% static "admin/css/semantic.min.css" %}" />
  {{ block.super }}
{% endblock %}
