Check if input changed fine tuning.

* Fixed issue when using streams directly and setting CheckIfChanged = true that IsChanged always reported true.
* Bin size pins will check whether their input changed independent of user settings - better default.
* Zip/Unzip/SplitAt and Select will do an early exit should their input not have changed (for strings and other reference types).
