OpenFOAM cases contain a list of boundary conditions for every field and boundary patch.
The files with boundary conditions may employ regular expressions to apply for multiple boundary patches simultaneously.
This modification allows the vtkOpenFOAMReader to find boundary information even in that case.
The vtksys::RegularExpression is used to match the boundary patch name. The last match in the list is the final one
(this is compatible with OpenFOAM behaviour).
