Fixed layout path for Ckeditor::ApplicationController for enabling rails 4 file uploading

[synthresin]

Ckeditor::ApplicationController class has no layout path definition,

so in Rails 4, Ckeditor::PicturesController < Ckeditor::ApplicationController uses your rails app's application.html.erb instead of ckeditor/application.html.erb as it's layout so required assets for uploading files are not loaded.

so I added layout 'ckeditor/application' in Ckeditor::ApplicationController

combined with pull request #276, file uploading in rails 4 will work well.

+1 why hasn't this been merged?
