New method CheckFaceSelfIntersection has been added to BOPAlgo_CheckerSI: now self-intersection of each face is found as well as pairs of intersecting faces; -method IntPatch_Intersection::Perform(S1,D1,TolArc,TolTang) is modified for more effective search of self-interasections in case of Surface Of Extrusion; -method IntCurve_IntPolyPolyGen::Perform(C1,D1,TolConf,Tol,NbIter) is modified to detect segments of intersections. Small correction. Test cases are corrected. Correction of compiler error Fix of regressions Names of shapes correction
