The delquad algo is now much more stable and nice

Two 3D meshers have been added. 

One is an embryo of the 3D delhex mesh which is an extension of delquad.

The other one is MMG, the mobile mesh generator of CECILE DOBRZYNSKI (Bordeaux I) and PASCAL FREY (PARIS VI). We are very happy that this new anisotropic 3D mesher is now available as an open source !!

cross field computataion ok in 2D
high order tools bugs fixed
wing-spline is now a correct geometry
meshing in two passes is now permitted (like in bamg)

- fixed MED node ordering
- polished 64 bit Cocoa Mac OS X FLTK version
- updated copyright

Add the option to prevent using metrics for high-order mesh generation (useful for some matched OCC models atm)

Adds an option to switch elementary and physical tags in loaded meshes, and fixes a bug with geo-mesh matching.

fixed newton in DG

* basic Abaqus INP mesh export

No commit message

in GUI to avoid flood of messages on mailing list (thx to Dave for this)

optimizing 3D meshes without also optimizing 2D meshes with Lloyd

introduced mesh.optimizeLloyd to fix this

No commit message

prototype "-watch" option to watch for specific files according to 
a pattern (use 'w' shortcut in GUI to test)

Added Navier Stokes & 2 test cases in DG
Added binary restart capabilities in DG
Added mesh renumbering option (-renumber)@

Added possibility to save distance to all boundaries (gmsh box.geo -2 -distance writes an additional distance.pos file)
distance is computed simply with ann for the moment

- invert #define logic (HAVE_MESH, HAVE_POST, HAVE_SOLVER, ... instead of HAVE_NO_MESH,
  HAVE_NO_POST, HAVE_NO_SOLVER)

better gestion of remote messages ("a la getdp")

added some more topological infos in high order elements (useful for DGM,
still have to be tested)

- moved GUI to FlGui + added experimental QGui to test Qt

- fixed most MSVC and gcc compiler warnings

- converted some remaining tabs to whitespace (that's why the patch is
  so large; please try to remember to indent with 2 spaces and not
  tabs when you commit stuff to CVS)

- merged modified patch from Konstantinos Poulios to allow saving
  physical/partition as element tags in mesh formats that don't
  support them natively

instead of implementation details (tetgen+delaunay & co)
