Setup Selenium automation test

[ValarMarkhulis]

• Setup selenium python script using Selenium IDE to do a test run
• Setup and use fake webcam script, that provides video and audio to the WebRTC client
• Use pyfiglet to generate logo and include in script
• Make test run headless or check, what happens when running script without display (using ssh to a VM and running the script)
• Do a requirement.txt for python deps and other software deps (Ubuntu/Windows)
• Make sure that the "media.peerconnection.ice.relay_only" setting is set to "true" under "about:config". Double check by looking a the end of the "about:webrtc" page.
• Check if the fake webcam stream is setup to use.
