Feature: Filter blocked/allowed requests in the statistics

[Mikey1993]

For me to unbreak a site has become broken by the Dynamic Filtering rules, I would want to be able to compare 2 runs:
1 with the blockage of 3rd party scripts/frames on
&
1 without the previously enabled blockage.

I would then be able to compare the 2 run results, and identify which domains needed to gray out/whitelist in the popup.
This also means that the "main_frame" in the statistics table should always be there for the visual comparison.

Yes I was planning to have fields to narrow visible results.
