"double" instead of "float"

The vtkSurfaceWriter places the "float" string in vtk files, where some versions of ParaView (specifically windows versions) require the "double" string to be present. As far as I can tell, all versions of ParaView work fine with the "double" string. I'm working on the master branch of OpenFOAM, commit 0770f9a3.

The following changes fix the problem:

Okay, I can go along with that and it should be no problem since we are writing in ASCII anyhow. However, could you please check if that is also the case for other VTK legacy output?

• sampling sets has the vtkSetWriter, which also uses float
• edgeMesh output in VTK as well
• foamToVTK with output in ASCII (This one is the most difficult to change)

@Prashant

@kvm - I hope it's okay if I slate this for the next release, rather than calling it a true bug for 1712?

mentioned in commit a89e2cdd

@mark That is fine.
