Add support for VersionX resource delta previews

[muzzwood]

I'd love to see a MagicPreview button on each VersionX resource delta allowing that point in time to be loaded visually.

@muzzwood and @Mark-H what about crowdfunding this via donation? Can you calculate how much money is needed?

This was an off-the-cuff comment I added when thinking about it. I haven't looked too in-depth at how involved it might be yet... but will do when I get a chance.
It might be "just" a matter of running a restore without saving in VersionX, and then giving that data to MagicPreview to use instead of the current resource.. but there could be a whole lot of problems with doing so that I'm unaware of yet.
One problem will be that assets previously used in a page may not exist at the same location anymore. But there's not much we can do about that.

@jenswittmann if you have any ideas on how to display preview buttons in the VersionX UI, let me know 😃

This preview feature may be toggled (true/false) in the system settings. This allows you to turn it off for certain sites.

I think WordPress has the same problem. But that is ok, because sometimes you want a piece of text or something like that.

Maybe keep it simple?

I want to put this on the roadmap. Maybe @muzzwood can calculate a dummy version and we can collect money for it 🤔
