Qt4 and Qt5 port of the ATSA library.

Qt4 has been already end-of-life for some time, so it does not make sense to target it any more. Qt5 support had been already introduced by previous commits, so it makes sense to target it by default. |

Partials modification formula fatures
=====================================
Predefined variables :
- P = number of partials
- T = number of frames
- p = current partial index [0, nPartials - 1] (av order)
- t = current frame index [0, nFrames - 1]
- a, amin, amax, amean = amplitude
- f, fmin, fmax, fmean = frequency
- h, hmin, hmax, hmean = phase
- v, vmin, vmax, vmean = selected magnitude (= a or f or h)
Predefined functions :
- A(p,t) = amplitude
- F(p,t) = frequency
- H(p,t) = phase
- V(p,t) = selected magnitude (= a or f or h)
Examples:
- frequency-flatten spectrogram around F(pr,tr) reference frequency
f = f*F(pr,tr)/F(pr,t)
Ex: xj220b.ats : f = f*F(38,42)/F(38,t)
