v1.8.1

Bugfixes

• Channel about page: remove /redirect in links to non-google sites. Normally youtube sends you through a tracking url when linking to non-google sites. This resulted in, for example, localhost/redirect?q=https://externalsite.com instead of https://externalsite.com in links on the channel about page. This is now fixed.
• Updated youtube-dl extractor for youtube, fixing js-signature extraction failure on certain videos
