Remove Raintale GUI's Download button

[shawnmjones]

Wooey has a confusing setup with respect to Downloads. We will be implementing a "View Story" button in #26 which will make the existing Download button redundant. We should remove the Download button so that it does not confuse users.

The code to do so is here:

raintale/raintale-gui/templates/jobs/job_view.html

Lines 40 to 53 in a2e219a

	<div class="btn-group status-completed-toggle">
	<a href="{{ job_info.archives.0.url }}" role="button" class="btn btn-primary">
	<span class="glyphicon glyphicon-download-alt" aria-hidden="true"></span> {% trans "Download" %}
	</a>
	<button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
	<span class="caret"></span>
	<span class="sr-only">{% trans "Toggle Dropdown" %}</span>
	</button>
	<ul class="dropdown-menu" role="menu">
	{% for archive in job_info.archives %}
	<li><a href="{{ archive.url }}"><span class="glyphicon glyphicon-compressed"></span> {% if archive.url|endswith:"zip" %}.zip{% else %}.tar.gz{% endif %}</a></li>
	{% endfor %}
	</ul>
	</div>

In a review during Monday's meeting, we decide to go in a different direction. Opened #34.
