Fixed SASS issue.  Fixed incorrectly displayed Labels question type.

	app/views/surveyforms/_question_fields.html.erb: Labels not showing correctly.  Looks like change to Surveyor
	that forced an update in logic.  Anyhow, logic too complicated - should be looking at question_type.  Change
	sections to use question_type later, did just Label for now.

	app/views/surveyforms/_survey_section_fields.html.erb: change to get add question button in proper spot.

	lib/assets/stylesheets/surveyor_gui.sass: change to get add question button in proper spot.
Converted paste question to unobtrusive javascript

	app/views/surveyforms/_survey_section_fields.html.erb: removed paste

	lib/assets/javascripts/surveyor_gui/surveyor_gui.js: added paste

	lib/assets/stylesheets/surveyor_gui.sass: got rid of

Converted add section button to unobtrusive javascript

	app/views/surveyforms/_survey_section_fields.html.erb: removed

	for add section ajax call.
