0024914: Micro edge is created during Boolean Operations

Browse Source 
class IntAna_QuadQuadGeo
The changes have been done to provide the treatment the cases
when the value of the angle between the planes is small and
the origin of intersection line should be refined.

class IntTools_FaceFace
The changes have been done to provide the treatment of faces
in cases when both are based on planar surfaces.
The UV-bounds have been extended to provide correct solutions
as it has been done for all other cases with plane-based faces.

Added test case bugs/modalg_5/bug24914
Modified length of result shape in test case bugs/modalg_1/bug10232
