added the ability to have playback paused when another app plays a transient sound (navigation, email notification, etc...)
added 'move to top' as an option, still doesn't do anything and isn't properly in the strings xml file.
Updated strings related to pausing playback to
1. have the title fit better
2. have better grammar
