renamed most gmsh* classes

- 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

Removed GSL dependency. Gmsh now uses blas and lapack for linear algebra
stuff.

- fix bb computation to avoid model jumping around when adding points in z=0 plane
- pass interpol matrices as ref

rewrote generic newton with fd.

last func using GSL is minimize_N.

removed parFromPoint and closestPoint from GEdge; replace their use in
cgns code by appropriate reparamMeshVertex calls (not tested: I don't have
cgns)

removed now unused golden section minimizer (brent), now unused

More "numeric" work: removed all traces of Numerical Recipes, as the
NR license is incompatible with our use. Replaced with Lapack for
LU/SVD. Still need to recode newt & brent.

untabify

A minimal Gmsh "null" model can now be embedded with no external dependencies

	-) A bug has been corrected in the MeshAdapt Procedure
	-) The 2D Delaunay is now Anisotropic
	-) 3D Sliver removal procedure has been improved
	-) Curvilinear mesh generation has been slightly improved,
	   even if it is still far from done

more cleanups

added Shewchuk's robust geometrical predicates (since they can be duplicated in
Tetgen/triangle I've put them in the gmsh namespace)

make negative physical entities behave like they're supposed to
