This patch fixes:

  * problem of node insertion along non-manifold edges in mmgs
  * errors in the Gmsh parser
  * missing reference edges in Mmg3d

This release includes:

    a review of the verbosity levels (from -1 to 5, -1 being totally mute for the libraries);
    a new management of the metric gradation along required edges to avoid very bad qualities when the prescribed metric doesn't match with the size of the required entity;
    the robustification of the 3D anisotropic mesh adaptation;
    the prohibition of the creation of spurious sharp angles on anisotropic surfaces;
    a new option (-lag) to perform lagrangian movement (with Dirichlet boundary conditions only) in a mesh.

Note: it fixes a bug in the beta-release (in matrix operators).
