Changes in the blockproc GUI. 1) Window position can be now set on creation. 2) Ctrl-C shortcut is now caught by the GUI so the processing loop is ended properly. 3) More JAVA exceptions checks
Added a possibility to specify a "transition area" in the slicing window approach.
Added a possibility to call blockplot without a frame object.
Changed the manual linking of MEXs in comp_*filterbank.c to a back call to Matlab.

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.

Backend lib now exports symbols properly without the explicit .def file.
Refactored dct, dst, gga, czt functions to take input arguments in a consistent way.
Refactored plans for the filterbank routines.
Removed some more unnecessary casts from void*
Added condition number check to test_dgt.

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.
