Florian Müllner bacfdbbb03 cleanup: Port non-GObject classes to JS6 classes
ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.
