Fixed star ratings for new version of simple_form/rails 3.2

	delete.gif: delete a star
	star.gif: show a star
	application.js: require jquery.rating.js to show stars
	application.css: require jquery.rating.css
	jquery.rating.js: star rating widget
	jquery.rating.css: formatting
	surveyor-gui.sass: suppress labels on radio buttons used for stars
	_question_fields.html.erb: change star fields for new simple_form syntax

	db stuff: picked up by accident.  Remove for next change
	log: picked up by accident.  fix later in .gitignore
fix for switching question types, remove extraneous code, fix edit question

	question_helper.rb: noticed a bunch of old evaluationrx code that
	is unecessary for this gem.  removed it.

	question.rb: Got a problem - text in the new version of surveyor
	sometimes has an entry of "default" which may not have been
	in earlier versions.  messes up switching of question types:
	original_choice not set properly because of it.
	change code to account for it when setting original_choice.

	blank.html.erb: needed for edit question functionality to work.
	added the file.
