Remove all events

[joekukish]

While removing an event, the function to remove needs to be provided. In most cases this functions are going to be anonymous.

doing

marker.off('click');

should remove all the available listeners for that event.

Agreed, it's a useful feature that's easy to implement, so I'll add this.
