cleanup: Use Function.prototype.bind()
When not using arrow notation with anonymous functions, we use Lang.bind() to bind `this` to named callbacks. However since ES5, this functionality is already provided by Function.prototype.bind() - in fact, Lang.bind() itself uses it when no extra arguments are specified. Just use the built-in function directly where possible, and use arrow notation in the few places where we pass additional arguments. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/23
