Provide quantitative operation statistics

[Anton-Latukha]

The moment, most people doesn't understand, know or see - what Decentraleyes is doing. And it is a main thing people evaluate installing/trying add-on.

Even I don't understand at first. Null-info/customazible-features helps. So I removed it, and installed it back, and played with it a bit back and forth.

If you provide statistic - it is going to be more obvious for people what it is doing and why it is helpful.

Like dynamic statistic, or a button (at least in Add-on properties) with statistic request calculation and "Processing..." for saving best-possible performance of addon.

Information like:
Volume of cached information in Mb.
Number of cached libs.

@Anton-Latukha Great points! Now that the core logic has been ported to WebExtensions, I'm able to focus on improving the user interface. Expect some improvements soon.

Interesting ideas, as long as there is no performance impact.
