* Update plugins/codemirror-editor from branch 'master'
  to bac9b336a326585accfc9a9eda7b5340e62783ac
  - Add simple.js addon
    
    Dockerfile mode requires this js file
    
    Also move addon's ontop of the modes, so that they are loaded before
    the modes to prevent js error's when the mode's require them.
    
    See:
