3a5edb5af5 FFTW wisdom is now built into jt9[.exe].
New optional argument to jt9: -w patience
Default is patience = 1

Example timing measurements for 130610_2343.wav:

patience  plan   execute
          (s)      (s)
-----------------------------------------------
   0      0.01     1.25  FFTW_ESTIMATE
   1      0.69     1.25  FFTW_ESTIMATE_PATIENT
   2     16.97     1.15  FFTW_MEASURE
   3    390.88     1.15  FFTW_PATIENT

Conclusions, consistent with expectation based on past experience
with similar FFTs:
  - First decode (in each mode) with patience = 2 is slow.
  - Speed advantage of patience = 2 is small but measurable.
  - No measurable advantage in using patience > 2.

Present mainwindow.cpp has "-w 1" hard-wired.

f07a960e2d Several decoder optimizations, including implementation of FFTW wisdom.
Notes:
1. Equivalents of wisdom1.bat will be needed for *nix and OS X.  (The
   version now added to the source .../lib directory is an example only.)
2. Installers should offer to run the wisdom1[.bat] script at installation
   time.
3. wisdom1[.bat] and fftwf-wisdom[.exe] must be installed in .../bin directory

b226f532d4 1. Dashed line between decoding periods.
2. Tweak four2a for compilation on 64-bit systems.
