search using API SIRENE for legal establishments

[risto42]

Won't get into odoo's messy contact model, but there are a few trivial difficulties with the API SIRENE lookup

1. Can only use with companies
   That's fine to get the registered company ('moral' person) initially with the affiliated SIREN, but for the other addresses which are registered establishments (having a SIRET) it's very difficult to explain to people that one has to click on 'company' in order for the API SIRENE lookup to work, then needing to set it back in order to not break accounting with a new false auxiliary account (frequently, especially with but not limited to public sector clients, establishments do not necessarily have distinct accounting).
   Fix: relax the restriction, API SIRENE searches can be used for companies, establishments as well as professionals not operating under a company structure (Entrepreneur individuel).

2. When creating establishments with a SIRET, it would be nice to be able to invoke the API SIRENE search directly from the popup to add an address on the company, saving the step of having to save the company, then backing out to find the new contact in order to complete the establishments details...

3. Finally there are a number of fields that are not filled in on the contact even though they are [already] retrieved via the API, such as APE and legal form
