In repo controller entry action, show the page for the file even if it's binary (so user still has access to history etc links). This makes it possible to use the entry action as the default when a file is clicked on

  # A simple JSON Encoder.
  # 
  # Example:
  #  CodeRay.scan('puts "Hello world!"', :ruby).json
  # yields

  #    {"type"=>"text", "text"=>" ", "kind"=>"space"},

  #    {"type"=>"text", "text"=>"\"", "kind"=>"delimiter"},
