[mod] result_templates/default.html replace embedded HTML by data_src audio_src

Embedded HTML breaks SearXNG architecture.  To modularize, HTML is generated in
the templates (oscar & simple) and result parameter 'embedded' is replaced by
'data_src' (and 'audio_src'), an URL for embedded content (<iframe>).
