feat(Controller): reset state method

[fiadone]

It allows to invalidate the current state so the next interaction won't be affected by the previous ones. It's particularly useful when, for instance, you have a carousel or a tab view containing interactable-by-gesture elements you want to be reset on slide/tab change.

This would be a reall helpful method... will it be merged at some point? Thx
