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/
