Add Youtube Cast reciever for remote control

[Bluscream]

It would be so great if myTube could be controlled with the Youtube app on my phone or tablet. Then i could use my PC hooked up to my TV as a Youtube player and can switch to the device almost seamlessly when i want to run around the house,
