- Fixed omission in xtract_bark_coefficients that was causing the output to be complete b/s! This fixed bark_coeffs and loudness feature which depends on it
- Changes to descriptor API: added is_delta and id. id corresponds to value in xtract_features_ enum and is useful for programmatic conversions between id and name string.

xtract_features_from_subframes()
- Added windowing functions (window.c)

only filled in freq_bands+1 values, when it should fill in freq_bands+2

xtract_init_fft() for creating plans, which have global scope. Updated examples to reflect the change. New configure option: --with-fft_optimisation (0 = FFTW_ESTIMATE, 1 = FFTW_MEASURE, 2 = FFTW_PATIENT).
