Motivation

When considering about embedding websites to MagicMirror, some websites cannot be embedded using iframe.

There are several reasons, one of that is HTTP response header X-Frame-Options: DENY by the websites makes iframe disable. This is needed for the internet security.

For MagicMirror usage, using WebView instead of iframe may resolve the problem.
