Title: Adding 4th argument on the Router.route() to set the context of the callback

Similar to the `Backbone.Events.on()` and `.off()`, the optional fourth argument of `router.route()` would set `this` for a route's callback function, giving dynamically created routes more flexibility in their execution.

Includes tests and documentation updates.
