Feature Request Extensions

[andyg2]

Would it be possible to determine what files are deemed to be html etc from the user files.associations key of settings.json For example adding the mustache for an html template like so?

  "files.associations": {
    "*.mustache": "html"
  },

Or alternatively to add interface or settings.js options for alternative extensions like so?

  "minify.html": {
    ...
    ...
    "htmlExtensions": [
      "html, 
      "htm",
      "mustache"
    ]
  }
