new -setstring and -setnumber command line options (to define parser variables without parsing, like in getdp)

Allowed the periodical voronoi diagram using the -microstructure option to deal with rectangle of arbitrary size. Xmax, Ymax and Zmax are to be specified as entry 3 to 5 of the input file.

TODO : avoid topological unconsistencies for (e.g.) cones when
delaunay meshing is involved.

removed clscale & perspective buttons from status bar

this amkes it easier to ship bundles (e.g. gmsh+getdp)

A new implementation for gamepad. option "-gamepad" is needed now. If no option, gamepad can be seen but nothing happens. 
All functionalities with "-gamepad", even if no gamepad is plugged when gmsh is launched. 
Gamepad can be plugged or desactivated during execution.

Removed the -q option in initial mesh generation (generates meshes that do not respect size field)

new "-open" and "-merge" command line args to select how to open/merge the files on the command line
