js: allow for multiple environment blocks in HTML

Browse Source 
Not that I actually need it, but it's just as easy to load multiple
environment <script>s from the DOM as it is to load one, so we may as
well do that.  Since only one element can have id="environment", we do
this by matching class="environment" as well.
