Hello.
I've added a new option to the form helper. With this option we can generate forms without authenticity_token tag. It is useful when we generate forms for some external resources like payment gayteways where names of fields are often restricted so forms with authenticity_token are not valid.
Usage example: form_for(@survey, :disable_authenticity_token => true)
