Implement a "keep-alive"

see #6 (comment) #6

getActivity seems to work as token so far. maybe theres an "official" token we can reverse engineer via wireshart?

I did not manage to capture readable packets between app and hub. I think they changed the way app and hub communicate in the new firmware and app version.
This is what the hub logs when receiving a command from the app:

"Aug 19 08:04:06.492 pimentoblue user.notice luaworks[126]: cs.c.websocketconnection [1655]: received json data {hbus={cmd=vnd.logitech.harmony/vnd.logitech.harmony.engine?holdAction,id=873e910e5863b36a#razorg#nexus 7-406-7,params={status=press,timestamp=916401,action={\"comma\n",

This is the same command from harmonyhubjs-client:

"Aug 19 08:15:56.535 pimentoblue user.notice luaworks[126]: cs.c.engine [1690]: processMessage(req): [ transport: xmpp ] [ id: 340611 ] [ cmd: vnd.logitech.harmony/vnd.logitech.harmony.engine?holdAction ]\n",
