Configuration of service plugins

Service plugins are configured in the main mqttwarn.ini file. Each service has a mandatory section named [config:_service_], where service is the name of the service. This section may have some settings which are required for a particular service. One mandatory option is called targets. This defines individual "service points" for a particular service, e.g. different paths for the file service, distinct database tables for mysql, etc.

We term the array for each target an "address list" for the particular service. These may be path names (in the case of the file service), topic names (for outgoing mqtt publishes), hostname/port number combinations for xbmc, etc.
