Feature request: panasonic_viera.py needs more keys

Can anyone implement/add more keys to https://github.com/home-assistant/home-assistant/blob/ecfe8e0a9a9f104fa5c37f37da37bf20b18b4fb0/homeassistant/components/media_player/panasonic_viera.py ?

For example from here:
https://github.com/florianholzapfel/panasonic-viera/blob/master/panasonic_viera/init.py

Thanks

Thin the deviceclass should be TV instead of mediaplayer. The tv-mediaplayer device has more capabilities than the mediaplayer it is now…
