Merge branch 'feat/viewmodel/scale'

* feat/viewmodel/scale:
  Add a ScaleFactor object.
  Switch from the actual servings spinner to the recipe scale spinner when going read only.
  Wrap view menu in object. Add accelerator. Move menu objects into package.
  Add the ability to enable/disable editing for recipes.
  Don't duplicate ingredientpanel code for a read-only version.
