Add mechanism to override non-blocking lists

[dhowe]

Describe the issue

Case: The users wants to enable a list for blocking that is not in AdNauseam's enabledBlockLists. There should be a way for her to do this.

Due to its complexity, this should perhaps go into some kind of expert interface. The user first needs to understand why we don't block all requests listed in such a list (b/c they would prohibit ad collection/clicking) and then want to override this behavior, either for a list already in the interface (e.g., EasyPrivacy) or one they might add manually (e.g., Peter Lowe's). The latter case is perhaps simpler as this can be an extra option when adding the list...

The only workaround at present is to install another, separate blocker, like uBlock, and then disable all lists except the one wanted for blocking; not at all convenient.

(see 999 as well)

This makes sense. I see some different ways of implementing this:

• through the hidden settings. We set the array of enabledBlockLists in the hidden settings and the user can change by themselves. the issue is that it would be really case sensitive, so not at all convenient.
• the best way I imagine would be a checklist next to the 3rd Party Filter Lists, so the user can dynamically check which lists they want enabled or not, with some sort of icon next to the list name perhaps.
