[RELEASE] Sage doorbell driver release v2.8.4

Porting SAGE Doorbell Sensor Driver help needed

I did some work on the driver from the OP. Someone else, that I can't seem to find to give proper credit, converted it to HE. I just added parameters to save custom names for each contact for logging purposes.
