Proposal: Ask the user when trying to play a sound while recording

Imagine you opened both a SoundRecorder and a SoundPlayer, maybe even in different spaces/projects. Now as a non-Squeak-Sound-expert, I found it quite irritating to press the "play" button while the recorder was active and just nothing to happen. Why don't ask the user which way he prefers?
