Userscript fix - disappearing dislike counter

[Moondarker]

Fixes #994, fixes #1013

I also backported rate bar fixes to userscript, added a setting to enable it, and kept it disabled by default - it has been broken for ages and I suspect users won't expect to see it

Also, now userscript won't be affected by #1008

Just checked it, you're right, @kokonguyen191, do you maybe want to clone my repo, branch off disappearing-counter-userscript-fix and pull request your fix back into my repo?

Alternatively I can commit from your name, if that's ok for you

Thanks a lot
