"Use blade comments" setting pollutes user config file

[Ingramz]

By default "use blade comments" setting is enabled, which will automatically add

".blade.html.php.text":
  editor:
    commentEnd: " --}}"
    commentStart: "{{-- "

to the user's config file. While this is not a great crime, because it is namespaced (scoped), it would be better if we could achieve the same thing without having to write into the config file.
