[HARDENING][VIDEO] Display VideoInstance's website _inside_ DeltaChat, not a browser

Feature Proposal
1
  1. Set https://example.com/my/#$ROOM as Video instance.
  2. Select “:” > “Video Chat”
  3. DeltaChat will send VideoChat website link
    4.,

Expected behavior

  1. DeltaChat open VideoTalk website inside the DeltaChat window.

Actual behavior

  1. DC opens my default browser (Bromite) which is blocking audio/video/WebRTC by default. I don’t want to grant those permissions because those can be exploited by 0-day JS vuln.

Therefore I want DeltaChat open the website inside the app using Android’s native WebView which should support WebRTC or whatevs. The optional HTTP proxy support to display such website is also wanted.
