Blacklist helper

[PetrK39]

Feel free to double-check it.
It works not as good as I expected with a few minutes of resource update delay but still better than copying in manually.
Ping me if docs need more explanation.

As the next step I would like to make some cleanup and then document all modules (maybe with some fancy 'jsdoc to md' github actions)

As a heads up I'm going to be really delayed in responding for the next couple of weeks. Will check this as soon as I can.

First run on a fresh install in a new browser in Violentmonkey 2.14.0 on Firefox 114.0.1, got this error:

Crashes the entire script.

Here's the snippet the error points to:

resources/gelbooru-overhaul.blacklistManager.js
221-            let nameList = document.createElement("datalist");
222-            nameList.setAttribute("id", "go-advBlacklistListNames");
223:            scope.blacklistItems.forEach(i => {

Still don't have time to look onto it properly, but posting this here for proper bookkeeping.

Looks like 'scope' is undefined. I'll try replace it with my recent discovery 'this.func = this.func.bind(this) when I get my hands on the code.
But I'm actually working on cleaning up code from things like that in a separate branch anyway

[PetrK39]

I just forgot to declare 'blacklistItems' in the class. Actually I got a different error but I believe this should fix it.
