Fix playlists

Fixes #320

[PlaylistBoy]

Hello!
Thanks for the fix. Unfortunately, it's not quite all the way fixed yet. Multiple shows can now be added to the "active playlist" (yay!) but the "update existing playlist" feature on the dropdown still remains unclickable (screenshot attached). It offers the option to "update existing playlist" but hovering over it/clicking it does nothing. This is on Windows 10/PC/Chrome.
Anyway, in the meantime, just having the multiple shows in the active playlist helps. It's a start! And thanks for your patience with me!

From your screenshot it looks like you are clicking Save on an "Untitled Playlist", which means it hasn't been saved yet, so that is why the "Update existing playlist" is greyed out. Please let me know if you have suggestions for UI improvement to make it more clear why that's greyed out.

I just double checked these features on phish.in and they seem to work. See attached screenshots. First one is from an existing saved playlist. Click Save and the default is "Update existing playlist". Empty out the playlist and click Save, and the default is "Create new playlist".

I updated the language slightly to hopefully make things a bit clearer.
