Patch for version 6.9.1 of Open CASCADE.

It includes the following commits:

Revision: 5a9dc37f84bb8c6c7ac1e43c1dbcf484b4261321
Author: emv <emv@opencascade.com>
Date: 22/10/15 9:00:54 AM
Message:
Make the possibility to produce empty result in case of any invalidity (spikes, self-intersections, faces inversion) optional.

Revision: aadba9a3f585693eddff1ea29b7063a08320ee23
Author: emv <emv@opencascade.com>
Date: 16/10/15 10:21:57 AM
Message:
Due to the small inaccuracy of the calculation of the bi-normal direction (direction inside the face on the edge)

the criterion on the coincidence of these directions has been weakened.

Revision: 3564da4b4d631c8ed627d7ca7697328d6c371aae
Author: emv <emv@opencascade.com>
Date: 15/10/15 11:52:23 AM
Message:
The option to remove INTERNAL edges from the faces of the result of Offset operation has been added into Offset API.

By default these edges will be kept in the result.
To remove these edges make sure to set the corresponding flag to TRUE when initializing the Offset algo.

void BRepOffset_MakeOffset::Initialize(const TopoDS_Shape&    S,
                                       const Standard_Real    Offset,
