Greasy Fork

To make it work with the latest updates, just need to make a couple tweaks:

• Replace all uses of location.search with location.hash, because YouTube seems to clear unrecognized query parameters now
• Replace the matches regex on line 35 with /(?:[#&])(user=(?:[^&]+|$))/ to account for using the hash rather than query
• Replace the linkmatch regex on line 28 with /\/(user\/|channel\/|@)(.+)|/ to support the new @ usernames

Didn't tested it but implemented this changes so everyone can have them

Thanks :)
