ChromeCast receiver with dash.js player sample (sender + receiver)

[jeffcunat]

Updated version of the ChromeCast sender and receiver sample.
Only Chrome sender has been updated for the moment.
The sender is able to initiate a cast session, play a stream, pause, seek, mute, change volume, toggle stats on the TV.

The receiver code should be hosted on the dash.js CDN in order to be available as a published app for ChromeCast.
=> everything inside samples/chromecast/receiver/**

ChromeCast app registering is done on https://cast.google.com/u/2/publish/
Then the APP_ID of the application will have to be changed in the sender sample

It is possible to test this sample without deploying the receiver on the CDN following these steps

• Register a ChromeCast device for development on the Google Cast SDK Developer Console
• Declare an app with url http://localIP:3000/samples/chromecast/receiver/index.html (with you local IP changed)
• Change the APP_IP in the sample by the one of the newly created app

Further works will come to modify the reference client and the Akamai control bar in order to add a cast button and use the control bar to manage the casted stream.

Feel free to make any suggestions...
