Project-Views, unnecessary routes 
Project-Edit with Project-Evaluator (not ready yet), deleted routes

Changed seed otherwise it won't work properly anymore. Notice: Seed-Users need to be confirmed, because Confirmation-Link won't work due HTML-escaping (needs to be fixed for non-html messages). See: http://stackoverflow.com/questions/4793504/rails-3-and-devise-escaping-mailer-templates
