📺 Implement chromecast support

On the UI kit for 0.0.2 we have the "chromecast" icon in the media controls lower bar:

Clappr has got a plugin for it. Could we use it @bent0b0x ? Make an own? Feel free to take this off the 0.0.3 project if it's unfeasible in short-time

Not sure how difficult this will be. We may have to write our own; I will update this issue when I start work on 0.0.3 and can better evaluate the task!

Is this still a priority? I just did a little research and you can only chromecast from a chrome browser, so not sure how big of a win this would be for us. That said, we can do it and display the icon only in chrome if we want!
