Changing route.data does not bind new observable to the url

[matthewp]

If we do:

route.register('{prop}');

route.data = new Thing();
route.start();

route.data = new Thing();
route.start();

route.data.prop = 'foo';

The URL will not reflect. There are a couple of ways to possible fix this:

1. If route.start() has already been called, setting route.data should teardown and bind to the new observable. In this case, the second start() call above wouldn't happen.
2. Create a route.stop() that does teardown. This puts it on the user to keep track of if they've already called start() though.

@matthewp Can this be closed now that 4.1.0 has been released?

[matthewp]

No, this wasn't done, I only did the route.stop() part.

Although I have no immediate intention of doing this.
