Remove nutrient hardcoding (nutrition table/edit mode) using new API

[teolemon]

The API is now available to use: https://fr.openfoodfacts.org/cgi/nutrients.pl

Currently the nutrient list is harcoded in

openfoodfacts-androidapp/app/src/main/java/openfoodfacts/github/scrachx/openfood/models/Nutriments.java

Line 30 in 46a8fbb

public final static String ENERGY ="energy";

However, we have a Taxonomy of nutrients we can refresh.

Also it doesn't show fields like Polyols

How could we get relations between them? (I'm thinking of minerals, vitamins, etc...) @teolemon

Also, if we create a map at runtime, we should change all occurrences like this

if (Nutriments.ENERGY.equals(nutrientShortName))
