Subject: Switch to Map address to state for contacts

This map should be empty in the future and updated based on the incoming
MQTT messages.

A list was not the correct data structure for that since it requires to
iterate over the whole list to find the entry with a certain address.
But this is required to update the state of an already known contact.
