[Gmsh] Lloyd mesh optimization for extruded geometry

I tried the lloyd optimization flag again with the current svn snapshot 
of gmsh and the reported issue of a segmentation fault for an extruded 
geometry now seems to be fixed. Furthermore the import to OpenFOAM 
worked and the OpenFOAM checkMesh utility reported no serious errors, so 
the geometry/topology of the obtained mesh should be OK. But I didn't 
(yet) check the quality of the optimized mesh.. :)
Anyway thanks for your hint,

Jonathan
