0029234: BRepOffsetAPI_NormalProjection produces INTERNAL edges and vertices

Browse Source 
Make the algorithm BRepOffsetAPI_NormalProjection use section operation instead of common to get the edge-result of projection to be in face restrictions.

Correct Boolean operation algorithm to produce correctly oriented result in the case of common between face and edge.

The algorithm ShapeUpgrade_UnifySameDomain has been patched to correctly gather same domain faces in a compound.

The TCL script snowflake.tcl has been corrected to get rid of dependence on the order of edges in the result of Boolean operation.
