This commit allows the user to navigate freely through a
survey with mandatory questions. He will be able to skip
questions and come back to them later. If he still hasn't
answered them at the final submit they will automatically
be displayed with an error message to invite the user to
answer them. The user can navigate through the skipped
questions with a button within the error box.
