Tweaking it.

Updated and tested it working.
Note that this is for a playlist. It will 'like' (or 'dislike') then 'next' every minute.
You may notice page reloads - that's for it to reload the script.

I removed the subscription requirement. It will work regardless if you're subscribed or not.

Also removed the page reload. Sometimes there's really short videos.

Removed channel subscription requirement.
Fixed working again.

Also you MUST be subscribed to the channel(s). This is just to prevent accidental votes.
