Walkout Song DJ iOS version 2.3.20 is available in the app store

[UpAllnite Software]

Version 2.3.20 was released from the App Store on April 20, 2018.

Fixed two long standing bugs:
- Issue that would repeat songs in the pregame list if the next song had never been scrolled into view since the last app restart (existed since original release)
- Issue where newly added items in the between inning, situation, pregame list would always appear at the top of the list after app restart (existed since 2014)
