Simplified SketchController.isReadOnly(..) method

Since the method is called everywhere with the following parameters

  isReadOnly(
    BaseNoGui.librariesIndexer.getInstalledLibraries(),
    BaseNoGui.getExamplesPath())
  )

the static calls to BaseNoGui have been inlined into isReadOnly()
removing all the duplications around.
