Title: Index paths for visible items improvement

Existing implementation iterated over the result from visibleCells and then called indexPathForCell for each cell both of which iterated over the _allVisibleViewsDict giving us a runtime of O(n^2)

new implementation just iterates over _allVisibleViewsDict like the methods of similar nature

My apologies for the merge commit, we're having some sub-module madness in the office
