add option to ioBroker out node to send custom settings to state

[thost96]

Hi,

it would be nice to add an option like the msg.stateType or msg.stateUnit property just for the custom field (seen in raw mode in the admin ui) of the state. I want to use this to set custom settings e.g. for Lovelace for some states I create on node-red scrips which would make my life easier.

"custom": {
      "lovelace.0": {
        "enabled": true,
        "entity": "sensor",
        "name": "sonne_azimuth"
      }
    }

So an option would be like msg.stateCustom = object like above. This would really help since manually create around 250 settings just for Lovelace is a pain.
