In software audio recording

[jenncross]

Teacher suggestion:
I had a teacher yesterday make a request for the ability to record student audio data within CREATE Lab Visual Programmer "like they do in Scratch". I just took a quick peak at that Scratch function (in the Sprite Sound tab) and I agree that such a function could really help streamline students' audio-expression-sequence programming process.

Shouldn't be to difficult, after I finish a few other things with the visual programmer I'll add this in

This is now done in the BirdBrain branch.
