Enable possibility to pass an empty prefix

[maoueh]

This feature could be used to create a main router that delegates unmatched paths to a "global" router. The main router would then only contains sub router definitions. I put an example usage at the bottom.

Tell me if it's something you would accept. Maybe there is already a better idea to achieve this. Sorry in advance for any missing things, first time I contribute to a JavaScript project :)

Example Usage:

var Router = Backbone.Router.extend({
    routes: {
      // Sub paths
      "projects/*subroute" : "routeProjects",

      // Fallback to MainRouter
      "*subroute" : "routeMain",
    },

    routeMain : function (subroute) {
        if (!App.Routers.Main) {
          App.Routers.Main = new MainRouter("");
        }
    },

    routeProjects : function (subroute) {
        if (!App.Routers.Projects) {
          App.Routers.Projects = new ProjectsRouter("projects");
        }
    }
  });

@maoueh thanks for this!

I'm glad to help out.

Another use case I found is that you can now use Backbone.SubRoute as your "main" router. For example, you can have:

MyApp.Router = Backbone.SubRoute.extend({
       ...
});

instead of:

MyApp.Router = Backbone.Router.extend({
       ...
});

And instantiating with new MyApp.Router(), the prefix is empty and with the patch, they are added correctly without the leading slash. No big deal but it's cool for consistency.
