Small things

plotfft and plotrealfft can now work with multichannel data.
Added option for filterbankresponse to calculate individual filter frequency responses.
Added some sanity checks for iwfbt and iwpfbt.
Building wavelet filterbank trees is now faster.

Added cqtfilters generator based on the cqt function.
Duals and tight frames to uniform AND painless filterbanks are now correctly handled by the painless alg.
Added check for painless condition to filterbankwin.
Added real-time CQT demo.
Modified real-time Erblets demo.
Changed FFTW flag in comp_filterbank.c and comp_ifilterbank.c from FFTW_MEASURE to FFTW_ESTIMATE, because FFTW_MEASURE sometimes hanged the execution.

The backend C library now consistently uses ltfatInt (ptrdiff_t or int) for array lengths.
fftreal moved to the backend.
dct and dst moved to the backend.
filterbank routines moved to the backend.
framematrix is now deprecated, and was replaced by frsynmatrix, which better reflect what the function does.

Some more work on comp_filterbank etc. test_erbfilters now passes for the filterbankdual. filterbanktight has probably a bug in it.

Converted wavelet filters to a format of firfilter.
Moved some stuff from comp_filterbank to comp_filterbank_pre.
Cleaned wavelets dir.
Added conversion function wfbt2filterbank which creates equivalent plain filterbank from a arbitrary filterbank tree.
comp_transferfunction now checks for existence of additional fields of the input struct. Mandatory fields are now .h and .offset for the FIR filter and .H and .foff for band-limited filters.

erbfilters can now create whole-frequency range filterbanks. Corrected the scaling in erbfilters to correctly account for the channel downsampling.

added missing semicolons to avoid Octave warnings; added 'redmul' option to erbfilters. By default it generates the highest possible downsampling rate while keeping the system painless.
