Add select button as pause/resume on chromecast via HDMI-CEC

[GoogleCodeExporter]

What steps will reproduce the problem?
Bravia sync doesn't have a dedicated pause button and therefor it's not 
possible to pause Chromecast app such as YouTube, Google Music etc. The select 
button should be able to pause/resume.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
Firmware 27946 

Please provide any additional information below.
