Add horizontal partition chart

[mr-manuel]

Previously I used rlerdorf/opcache-status, but now that is a (bit) outdated. What I really liked was the horizontal partition chart, that made it very easy to see to which folders the scripts were associated.

Would it be possible to add this or something similar? Maybe you can only copy that part of the code, which is not that much.

Then when clicking on a bar, it zoomed in.

I haven't used opcache-status before, so am not familiar with that particular interaction, but that's a definite possibility, @mr-manuel. That's kind of like a horizontal treemap kinda of graph, right? I might have a look around for a js library that does one I like, and that doesn't add too much extra to the page load, and see how it looks.
