ENH: add -tri (triangulate) option to foamToSurface, surfaceMeshConvert

Browse Source 
STYLE: drop surface extraction from foamToStarMesh

- retain surfZone names when writing surfaces
- remove surface extraction/writing from meshWriter since it now
  duplicates what the meshedSurface class can do.

Description
Writes polyMesh in pro-STAR (v4) bnd/cel/vrt format
Alternatively, extracts the surface of the FOAM mesh into
pro-STAR (v4) .cel/.vrt/ format.
This can be useful, for example, for surface morphing in an external
package.
The cellTableId and cellTable information are used (if available).
Otherwise the cellZones are used (if available).
