add new fields and alter new identity form significantly, translating and formatting
add second household head fields and alter the new identity form to be able to toggle one household head set on and off
Fixes: "4) Change "can't be blank" validation to French: "rempliseez cette case"
     -The "validates" command wouldn't accept a message in the same way the "validates_format_of" does"
Fix : "5) The "with: /[a-z]/" command for "validates_format_of" only seems to check if there are any letters in the field, even if there are numbers"

-Note: I currently permit spaces. To disallow spaces, change /\A[a-zA-Z'\s]*\z/ to /\A[a-zA-Z']*\Z/
