Support embedding Discourse in an iframe

[denvergeeks]

Two settings would be required if you wanted to, without restriction, embed Discourse in iframes:

1. Un-check the CSP restrictions in Settings
   

   

2. Enable a hidden site setting allow_embedding_site_in_an_iframe

cd /var/discourse
./launcher enter app
rails c
SiteSetting.allow_embedding_site_in_an_iframe=true
exit
exit
