Resolve issue #289: implement NS-provided display of fat/protein in graph

- Resolves (Trio issue #289)[https://github.com/nightscout/Trio/issues/289]
- Implements Nightscout's provided graph display for fat and protein in meal entries
- Trio had partially implemented this but did not pass fat and protein values to Nightscout (it dropped them but carried carbs)
- This PR follows the identical pattern used for carbs and carries fat and protein values along for NS to display
