[Garbash]

Current behaviour: In descartes.rhizi.net: ['person', { 'title':'Personne', 'attributes': ['description', 'email', 'image-url', 'name', 'url' ], }],

• Node type name displayed in input bubble is "person" should be "Personne"
• Node type name displayed in property menu is "person" should be "Personne"
