Make uncomplete products searchable

• Add raw JSON output as hidden by default text to enable search engines to index incomplete products (it could be collapsed and shown after the click of a button)
• Add hidden field to enable the internal search engine to find incomplete products

Expand Open Food Facts coverage by adding additional information in new fields

• Description
  • some products are very talkative
  • it can be a first step before we add the other fields
• Cooking recommandation
• Storage recommandation
• Postal address of the producer
• Postal address of the distributor
• Email Address of the producer
• Email Address of the distributor
• Phone number of the producer
• Phone number of the distributor
• Website of the brand
• Ingredient percentage
