Add civility options for professional entities (company, business, SCI, syndic)

I'd like to be able to add additional civility options in Revel'home to better identify my business customers. Currently, the civilities available only cover private individuals (Mr., Mrs., etc.) I'd like to be able to add or select civilities such as: - Company - Business - SCI - Syndic This would enable me to better manage my professional customers and have documents and communications more adapted to their legal status.
