Tested the application, seemed to not get hung up like it did before. Need to remember to change the database back, since it currently is running the Vacation Choice survey
Fixed the issue where refreshing or entering invalid answers for the scenarios give the respondent a new scenario.  Now the same scenario should be shown.

working as intended (i.e. was showing even though the first question was
shown and was numbering previous questions incorrectly)

Added a question about current vehicle size
Added response? method to questions and changed survey_script.rb to use response? rather than check whether the question was a dummy, calculation, etc.
