Adds an option to pause audio while audio focus is lost.  This is helpful when using navigation apps (for example) so that you can hear what the navigation app says and you don't miss whatever was being said on your podcast. Without this setting checked they may wind up talking over each other, which can be confusing.
updated name of the preference to use 'FocusLoss' rather than 'Notifications' to more accurately reflect what it does
