Boolean Operations - Improve Edge/Face intersection procedure to take into account the coinciding edges

For the case in which the coinciding edges intersect some face the algorithm performs computation of the intersection of all coinciding edges with this face. It is necessary change this procedure to intersect only one edge from the block of coinciding edges with the face, add the interferences for all edges and:
1. In case of intersection compute the parameters of the common range and intersection vertex on all edges from the block;
2. In case of overlapping add the face to the list of faces of the common block.
