Batch Listening

[amiantos]

From a user...

I love Numu but I was wondering if there was a way to check off entire artists or hour while collection as listened because I just started using the app and added a bunch of artists I’ve already listened to. If this feature doesn’t exist, it might be a good idea for a future update.

I'm inclined to give users the ability to mark an entire artist as listened to. Not sure about entire collection, but maybe. Some/a lot of UI changes would have to be made to the main releases screen to add an "edit" button or some sort of batch edit mode.

Might be related to #45 if we add a "listen to everything" feature to that screen.
