Provide option to render Recaptcha as a form type #60
Description
Currently, form error related to recaptcha validation is bound to the form itself, making it impossible to display the error right next to the recaptcha widget (if checkbox widget is used, for example).
In addition to having the option to bind the error message to the form, it would be nice to have a dedicated form type which can be used to render the recaptcha widget, which would enable error message to be bound to the form field itself instead of the entire form.
