Feature audio message

[UberNomad]

Description

Adds a notification that shows if the user hasn't clicked into the program iFrame window and SplashKit audio functions are being used. Essentially, it reminds the user to click into the Execution Environment so that they can hear the audio playing. This is only a problem on the C++ runtime.

Fixes # Show message to user requesting them to click into the Execution Environment iFrame to get audio working
