Vetur code completion for app extensions

[moander]

First of all thank you for all the hard work. Quasar framework is awesome!

Vetur supports Quasar Framework but for app extensions you need to add quasar as a dependency:

  "dependencies": {
    "quasar": "*"
  }

For app extensions I think the proper way would be to add it to devDependency but Vetur does not currently support that so I'm reporting this for the reference.
