Title: Renamed property presentingViewController to avoid overlap

presentingViewController is a property of UIViewController (since iOS 5) and should not be overlapped.
Changing the name to presentingFSViewController (to keep consistency with presentedFSViewController) fix this issue.
BTW, on iOS8 this overlap generates a recursive loop of assignments.
