Alternative to https://github.com/spotify/HubFramework/pull/283

Traversing the view hierarchy in search of specific class that handle touches is not really scalable.

This is an alternative solution.

@mumme @marmelroy I prefer this solution a lot to what Hub framework does and what was added in #283! Seems like a better way to do it.

This solution did not work for the segmented control case.

@mumme, did a little investigation and it appears that the reason this doesn't work is that UISegementedControl doesn't implement any gesture recognisers and captures touches directly (thanks Apple).
