key/value resource translations

I have detected this on resource details page (file: /package/resource_read.html):
If you click on "Aditional Information / Show More" link, CKAN shows key/value pairs from resource, this is because there is a for loop into resource_read.html file that shows them, but texts never is translated.
This is because it has not correct tags in resource_read.html file.

To solve this we have to replace in resoucr_read.html line:
          <tr class="toggle-more"><th scope="row">{{ key }}</th><td>{{ value }}</td></tr>
with:
        <tr class="toggle-more"><th scope="row">{{ _(key) }}</th><td>{{ _(value) }}</td></tr>

and write translations keys and values on translation file.
