This reverts commit 82682dfc.

Remove useless variables for common object

FIX : remove deprecated property 'libelle' on product object

Fix : missing link to category into product card.

Added missing translation of categories' "Translation" tab

Fix #2769

Rename $nom into $label
Add missing html class to show description as required

Fields name / civility / ... are nonsense for a lot of objects into Dolibarr.
They could be defined for each object instead of into the common object class.
