Updates from Evgueni Tcherniaev. All files under source/geometry/management
match the versions in the trunk of the G4 SVN repo as of 27/06/2017.
All files under source/geometry/solids/CSG match the versions in the trunk
of the G4 SVN repo as of 27/06/2017, except for G4Trap.cc where a FatalException
in G4Trap::MakePlanes has been replaced by JustWarning. The G4Trd class
has been fixed to accept Dx/Dy equal to zero where appropriate.
Under source/geometry/solids/specific G4PolyCone and G4Polyhedra match the
versions in the trunk of the G4 SVN repo as of 27/06/2017. G4VFacet,
G4TriangularFacet and G4QuadrangularFacet have been updated, but modified
to be compatible with G4 10.1.p03.
