Rails 4.2 model and controller fixes

- Wrap all scopes in lambdas (required in Rails 4)
- Move scopes after associations in page.rb (evaluated at load time in Rails 4)
- Convert association :order options to lambda syntax
- Remove attr_accessible from page.rb and user.rb
- Add Strong Parameters: user_params in UsersController, node_params/page_params in NodesController
- Fix clone_attributes_from: exclude id/page_id/timestamps when cloning translations
- Fix redirect_to :back → request.referer fallback in nodes_controller
- Fix node_path/publish and unlock actions: pass @node argument
