Changing some patron management rules (#1631)

Changing some patron management rules (#1631)

- the guarantor is no more readonly: it can be typed manually
- useless fields in case of an institution are removed (like DoB, Firstname, gender)
- reintroducing the relashionship select, that was missing in the template (but was handled by the pl)
- moving B_phone to a more logical place (with alternate coordinate)
- reintrocing contactnote in "alt contact"
- changing the select_city behaviour : when a city is choosen, the zipcode & city are automatically filled.
