0026699: Wrong section curves

Browse Source 
1. Algorithm of Restriction line processing has been improved in IntTools_FaceFace.cxx file.
2. Algorithm of checking, if Restriction line and Walking line are coincided has been improved in IntPatch_ImpPrmIntersection.cxx file.
3. Algorithm of extending check if starting point of Walking line is a tangent point has been added.

Small correction of some test cases.
Creation of test case for issue #0026699.
