SoundPlayer+LibDSP: Move the FFT implementation to LibDSP

Browse source 
LibDSP can greatly benefit from this nice FFT implementation, so let's
move it into the fitting library :^)

Note that this now requires linking SoundPlayer against LibDSP. That's
not an issue (LibDSP is rather small currently anyways), as we can
probably make great use of it in the future anyways.
