Remote control support

It’s sometimes desirable to have an ability to pause the playback, or skip current track in a fast way, without a tablet/phone.
I have an “air mouse” remote control which is not an air thing actually, but acts as a mouse buttons plus some computer keyboard keys pusher.
It works fine with Kodi but Volumio does not reflect its buttons excepts OK (== Enter) one. It’ll be fine to support such PC-mediacenter remotes.
