iFrame support

[Kaynoux]

It would be nice if I could use UpSnap embedded as an iframe on other sites. Currently this is not possible.

Refused to display '(URL)' in a frame because it set 'X-Frame-Options' to 'sameorigin'

Found a workaround: I used nginx proxy manager to change the X-Frame config. It works after adding this line
proxy_hide_header X-Frame-Options;

This was the real deal! thanks for sharing! was looking for this as I wanted to show upsnap directly on my homeassistant control panel and this was the only good response.
