ENH: use double for VTK legacy output (issue #891)

Browse Source 
- some paraview versions (eg, on windows) don't support float, only double.

  This mostly affected the vtkSurfaceWriter.

  The foamToVTK is also affected, but since it also supports the XML
  output formats (vtp, vtu) these can be used instead.

Description
A surfaceWriter for VTK legacy format.
Note
Uses ASCII-only output.
All data are written as \c double due to portability issues
(paraview on window).
