Feature request: Mute toggle possible?

[maciboy]

Hi,
I really like this plugin and the successor …-x by @skrollme
From the python script needed for pairing, I learned that toggling mute seems to be a possible command. https://github.com/suborb/philips_android_tv
Would it be possible to add a mute toggle as a third switch besides power and Ambilight?
I think it would be a great addition ;)
