Title: Enable class inheratence in CoffeeSCript

pull request for #1314 to get leaflet classes to extend right in CoffeeScript, based on [this update to backbone](https://github.com/documentcloud/backbone/commit/1d57168c8f436f1f9b20a5fa7f13495610931b22) which added the same functionality to backbone.
