`fluent3DMeshToFoam` throws fatal error when converting ASCII msh file to OpenFOAM polyMesh.

[TimoLin]

For newer versions of fluent meshing, the ASCII mesh files contains following lines starts with (cad: like

When using the conversion tool:

fluent3DMeshToFoam ./test.msh -scale 0.001

It throws the following fatal error:

Zone: 49 name: outlet:wall_comb:-----:feature.49 type: boundary-edge.  Reading zone data...done.

A fixed version is created in applications/utilities/dfFluent3DMeshToFoam. Use it as the same as fluent3DMeshToFoam.
