Experiment with Hover Preview on Options

[georgeolaru]

Paste app has a surprisingly intuitive UX flow when previewing options which use the "hover" event instead of "click & try".

I think the same approach could be applied to some of the options from a block and make user decision easier to take.

@razwan have a look and let's see how it feels in Gutenberg context.

@razwan already made a prototype on this branch: https://github.com/pixelgrade/nova-blocks/tree/13-options-hover-preview

It feels great so far (at least for the Text Alignment) —  let's keep this open and look forward to testing other options that could work in a similar fashion:

@georgeolaru looks like we cannot handle mouse events on some controls like selects and radio buttons (probably others also) in which case we would need to implement our own controls.

We could try to replicate the radio control component and add the preview feature just to have all the controls for the Media Card block working properly. I don't think implementing the feature this way is a good idea in the long run.

I also don't think this kind of feature would get implemented in Gutenberg anytime soon but we could try to stir up some discussions
