GPL -> General Public License

License stuff

add ;

Indented all source files using utils/gmshindent

Add some indent directives

Fix some dependencies + enable GSL (so that more people test it).

This is a pretty big commit.

- The Numerical Recipes routines have been moved to their own
subdirectory: NR/

- These routines are now completely optional. Configure will
determine if they have to be compiled in (if it's a non-free version
of Gmsh) or if we should use the GSL routines instead.

- The GSL routines are there. Well, sort of. The SVD stuff works
great, but the minimization routines still need more work. The whole
infrastructure is there, though: we can already compile a fully GPL
compliant version of Gmsh by removing the NR subdirectory (or by
specifying --enable-gsl to configure).

- I also simplified the options passed to the compiler (OPTIM and
FLAGS).

That's all for today folks...

Add comment for LITTLE_ENDIAN problem

Don't use LITTLE_ENDIAN, it may be defined on Macs and cause the
colormap problems. Define and test _BIG_ENDIAN instead.

Change NODLL to _NO_DLL

Clean up VERSION_FLAGS and OS_FLAGS (use HAVE_FLTK instead of _FLTK,
remove _BLACKBOX, etc.)

New makefile system based on autoconf. Only tested on Linux right now.

Note on Combine view + save bug

Fixed a couple of typos + copyright dates
