findDOMNode will be deprecated

[dsempel]

Starting from React 16.6 it is deprecated in StrictMode and it will be deprecated from React in the future. Here is some more information about this.

The docs state the following:

Normally you don’t need this because you can attach a ref directly to a DOM node.

The warning in StrictMode:

Warning: findDOMNode is deprecated in StrictMode. findDOMNode was passed an instance of VisibilitySensor which is inside StrictMode. Instead, add a ref directly to the element you want to reference.

Maybe we should implement some ref pass through technique to bypass this issue? The DOM node should be accessed anyway though.

@ameerthehacker Any news on when #242 will make it into an npm release? The build files in 2.6.2 still have the findDOMNode code.

It would be great if we could get a release with this fix!

I do believe that it's an important fix that needs to be accomplished. These warn are being very annoying.

@rafaelcamaram I totally understand it, the fix has been in beta for few weeks now already and I will release it tomorrow
