Refactor PanResponder example to avoid componentWillMount()

[benadamstyles]

React Native v0.54 uses React v16.3, which deprecates various lifecycle methods including componentWillMount(). In the PanResponder docs, the recommended approach is to set up PanResponder methods in componentWillMount(). Could the docs now be updated with the recommended replacement approach?

I could take this on. I imagine the recommended approach would be initializing state or in the constructor.

However, would it be best to add a description or a link describing the various lifecycle changes either in Update on Async Rendering or deprecates various lifecycle methods that @Leeds-eBooks mentioned?

I mention this, because I have beginners in mind.

Thank you for taking this @andrwsalcdo.

Where would you add this? If it's inside the PanResponder docs, I don't think it worth mentioning as after the refactoring, beginners won't notice the changes from the previous version.

ah fair, but for those beginners that were learning from outdated resources? eh, it's probably a bit of a stretch, but I thought I ask.
