Fixed OSC trace being reversed up-down
Moved output modules to dedicated folder
Added FFT module (skeleton)
Fixed fft help skeleton
Updated preversion number
Added FFTW as dependency & linked library
FFT Init

Started FFT module
Initializes the FFTW plan, executes it once, then quit.

The test inputs random numbers in the buffer, and the output seems to be
bound into -127 and +127 (to check !)
Added basic FFT
FFT Overlap
fft vars + smooth output

Modified FFT main routine to use variables instead of hard written
values to be able to set them later directly in the dedicated parser.

Also, added blur to the drawn pixels to smooth a little the output.
FFT Color shades

Calculates the color from the shades table
FFT Shade working

Modified color shade calculation from the input value
The input value must be bound between 0 and 100.
If it's more than 100, it will be clipped to the maximum value for the
shade (last percentage defined - 0.1 to avoid calculation bug)
FFT Parammeters handled by the parse_fft function
FFT: modified default FFT
Modified default color scheme
VIM Session with NERDTree
Modified fft help text

Included ranges in fft parser help for --color
Fixed alpha channel for OSC color dot & comment unneeded in fft
Merge branch 'fft_mod' of ssh://homer.art-software.fr/git/visound into fft_mod
