Playlist should be sorted alphabetically

[kai-wng-uos]

We need a default way for sorting playlists in SOP. At the moment, the order of playlists may change randomly with every new playlist created. This is confusing. For simplicity's sake, I'd suggest alphabetical order.

I would suggest going by creation date instead of alphabetical, so that newly uploaded videos are always on top of the list and therefore easy to find.

This doesn't refer to the way the videos are sorted, but the playlists (in the sidebar) are sorted. You can already sort Videos via the menu in the sidebar, but there is currently no way to manually sort playlists afaik.
