Webcam in Cindy JS

Note if running from a local machine Chromium/Chrome are preventing camera access due to security concerns.
You can work around this by launching ./node_modules/.bin/st -l -nc and then visiting http://127.0.0.1:1337/examples/webcam1.html.
Alternatively, you can also run Chrome with the --allow-file-access-from-files flag.
This shouldn't be necessary if the example runs on a webserver.
