saveOBJFile(... PolygonMesh ...) writes faces without spaces

[sidch]

The function

int saveOBJFile (const std::string &file_name, const pcl::PolygonMesh &mesh, unsigned precision=5)

in file io/src/obj_io.cpp writes the indices of each face without separating spaces when the face vertices have associated normals. The bug is in line 369:

fs << mesh.polygons[i].vertices[j] + 1 << "//" << mesh.polygons[i].vertices[j] + 1;

The fix is easy: output an extra " " after mesh.polygons[i].vertices[j] + 1.

HI @sidch, thanks for the bug report. As you found the fix already, can you send a pull request with it? That would make it easier for us to integrate it and give you the credits as well ;). If you need help with sending pull requests, don't hesitated to ask.
