Description of your issue, suggested solution and other information

The JSON response the periscope extractor uses to download playlists has changed. There used to be a list of broadcasts that had an ID. Now the JSON only contains a list of broadcast IDs.

Changing this:

entries = [
    self.url_result(
        'https://www.periscope.tv/%s/%s' % (user_id, broadcast['id']))
    for broadcast in data_store.get('UserBroadcastHistory', {}).get('broadcasts', [])]

to:

entries = [
    self.url_result(
        'https://www.periscope.tv/%s/%s' % (user_id, broadcast))
    for broadcast in data_store.get('UserBroadcastHistory', {}).get('broadcastIds', [])]

fixes the issue.
