Send push notification to user when he is added to an album

[benny-shotvibe]

This should be similar to the push that is already sent for new photos:

Two different types of messages for the user who created the album(used only for doing an immediate sync between multiple devices of the same user), and for everyone else

[benny-shotvibe]

We should only need to add a single new function to device_push module: broadcast_new_album

Ignore my previous comment. Please use the following definitions for 2 new functions in photos_api.device_push:

def broadcast_added_to_album(album_id, album_name, adder_name, user_ids):
    rq = {
            'user_ids': [str(id) for id in user_ids],
            'gcm': {
                'data': {
                    'type': 'added_to_album',
                    'album_id': str(album_id),
                    'adder': adder_name,
                    'album_name' : album_name,
                    }
                },
            'apns': {
                'aps': {
                    'alert': adder_name + ' added you to the album ' + album_name,
                    'sound': 'default',
                    },
                'album_id': album_id
                }
            }
    send_message_or_log_errors(rq)

def broadcast_album_list_sync(user_ids):
    rq = {
            'user_ids': [str(id) for id in user_ids],
            'gcm': {
                'data': {
                    'type': 'album_list_sync'
                    }
                },
            'apns': {
                'aps': {},
                'type': 'album_list_sync'
                }
            }
    send_message_or_log_errors(rq)

• broadcast_added_to_album should be sent to a user(or multiple users simultaneously) whenever someone adds them to an album. (Including when they are added added directly to a new album)
• broadcast_album_list_sync should be sent to a user when he himself creates a new album, or when he leaves an album. (This is a silent push notification that is needed so that if the user has multiple devices, and he creates an album on one of them, it is immediately synced to his other devices)

[benny-shotvibe]

For broadcast_album_list_sync it might be best to change the argument from a list of user_ids to just a single user_id, since I can't think of a scenario where it will be needed to broadcast this event to multiple users
