That's the way I have to check whether the event has been added to requested element and callback through skrollr or from outside. If I remove this loop then `_removeEvent` will be able to detach/remove any event to any element no matter it was added by skrollr or from any other external process/behavior.

`_removeAllEvents` does a similar loop but that's just in order to figure out which events have been added by skrollr and then make the call to `_removeEvent` on each one of them.

I can get rid of the `_removeEvent` loop anyway if you still think so, just let me know.
