FFT Plugin: Revamp the main code to rid it of 64-bit math. Use 32-bit kiss_fft_scalar because 16-bit integers are generally a poor choice for computation on-target. Simplify display code to speed it up. Add logarithmic frequency display (need keymappings, guessed on some). On dual-core, perform FFT on COP. Add some support function to fixedpoint.c. ... and stuff.
