meta-digi-dey: webkit: add recipe to install webkit version of 'connectcore-demo'

The Webkit version of the ConnectCore demo implements some new functionality:
- The COG browser is automatically started when the device boots loading the demo in the
  primary display.
- A new Multimedia section is available to reproduce some demo videos and WebGL examples
  in the device's browser.
