Remove or fix naturalScrollLimit option

While this option seemed like a good idea, its causing errors related to refresh on scroll since it removes the scroll related refreshes.

Technically this means Treebeard is adding refreshes in scroll that are not related to scroll so they need to be separated.

Another option is to remove natural scrolling since it's not in fact being used anywhere.

Otherwise looks good. Just that it might be more efficient to not add "::" and "" to tags in the first place.
