GJS camelCase methods (at least)

[Andrea Giammarchi <andrea giammarchi gmail com>]

I've updated to GJS 1.50 (and I've seen 1.54 is actually the latest) and things are becoming better and better on daily basis.

Seeing that I can also extends Gtk classes without needing the (obsolete?) Lang namespace is wonderful, yet beside having almost fully implemented ES2015 syntax I've seen zero changes in terms of "camelCasization".

I've created a method that does only that [1] so that I can write code like the following one and see it working without a glitch.

```js

const Gtk   = imports.gi.Gtk;

Gtk.init(null);

class Dialog extends camelPatched(Gtk.Window) {

  constructor(...args) {

    super(...args);

    this.connect('show', () => {

      this.setKeepAbove(true);

      Gtk.main();

    });

    this.connect('destroy', () => Gtk.main_quit());

  }

}

const win = new Dialog({

  type: Gtk.WindowType.TOPLEVEL,

  window_position: Gtk.WindowPosition.CENTER

});

win.setDefaultSize(200, 80);

win.add(new Gtk.Label({label: 'Hello GJS!'}));

win.showAll();

```

Now, I understand that properties and configuration objects might require huge time/resources investment but can we please consider a migration plan for at least camelCase methods?

Or could we at least add a method that does basically exactly the same thing I am doing so that GJS could offer a more JS friendly environment?

Thanks in advance for any sort of outcome.
