Show domain for channel links
Currently it returns an array, so the app shows the array index for each link,
rather than the links themselves.
Do some rudimentary parsing to extract the domain of the link and show that
instead.
isChannelUrl: exclude album and tracks
So the app doesn't open the artist page when you open an album or track.
Reorganisation
Split the complex map for videos out of toPlatformPlaylistContents.
Remove semicolons
Force of habit
Implement getHome
Using the notable albums feed from the homepage.
Fix playlist titles from channel page
Fix artist url in getContentDetails
Fix getChannelContents
This was accidentally based on the /merch page of an artist, which is sometimes
the default page. Always request the /music page.
Add script public key and signature
Implement getChannelContents
Add functions for getting thumbnail URLs
Add keep-alive to more http requests
