Heavy work on IPC.

Browse Source 
We will now have a broker (aqhome-data) which stores data and distributes
value change messages among connected clients.
aqhomed will connect to that broker and send its values there.
aqhome-mqtt will also connect to the broker and send its values there.
Other clients can later connect to check for changes and react according
to rules.
