Moved phase locking/unlocking from Matlab to C

This concerns both dgt and dgtreal on reg. lattices.
The operations were very slow in Octave.

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.

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.

Fixed time hop sizes in plots in examples in erblett and cqt.
Renamed framematrix to frsynmatrix.
framenative2coef does not fail anymore if the frame object does not contain native2coef field.
Forgotten oct/

Rewritten INSTALL instructions.
Sliding spectrogram plot now zooms using mouse wheel.
Major rewrite of the buildsystem ltfatmex and some Makefiles.
LTFAT can be now easily compiled for Octave on Windows.
New ifilterbank_* routines as OCT files.

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.
