EgtInterface 1.6b5 :

- in CurveCompoByChain si cancellano gli originali solo se ok
- in EgtModifyCurveThickness gestito vettore di Id
- aggiunto Snap Point Baricentro (Gravity Center)
- aggiunte EgtCurveArcRadius, EgtCurveCompoCenter
- aggiunte funzioni lua EgtGP, EgtET, EgtCurveLength, EgtCurveArcRadius e EgtCurveCompoCenter.
