Make CSS image-overlay class pointer-events: none (Imagus and HoverZoom support)

[krisser143]

Even though we are getting a total website overhaul soon, I really think that this is a small enough change to incorporate to support Imagus and other image enlarger plugins. Whenever you hover over an image in the images search, the weird overlay thing pops up, effectively stopping Imagus and HoverZoom from knowing that you are hovering over said image. By simply making the overlay's class "image-overlay" pointer-events: none it works fine. I've already tested this, and it changes nothing in terms of functionality.

 

I'm really looking forward to the website overhaul, it's going to be great!
