Request: "load more" option for reviews

I'd like to show a few reviews on the main page (preferably one row of three) with a button to load more (just like the blog section offers)

I didn't dive in the code yet so I don't know how easy it is to transfer that functionality over from the blog section. And I'm no code warrior either so I'll just post it here first...

If I manage to create this myself one day I'll create a pull request myself ofcourse...
