forgot make depend in NR

We cannot distribute Metis until we ask permission to Karypis.

JF: tu t'en charges ?

make depend

moving all external code to contrib subdirectory

apply patch from the Debian people

mention the variables file at the end of the configuration process

use it now with -partition N for N partitions
only works with tets and triangles
output should be added (useless for now)

mention bug on Windows without Cygwin when reading binary post-pro files

explain #list[]

Fixed horrible performance of vertex array creation on Windows for
very large post-pro views (> 1 millon triangles). The bottleneck is
the memory reallocation, which is 100 (?) times slower than on
Linux/Mac. Introduced some simple heuristics to estimate how many
primitives will be displayed. A prepro pass (like for smooth normals)
would be a more elegant solution.

use the autoconf uname

First batch of changes so that we can compile the code on windows
without cygwin. With these changes gmsh compiles and runs cleanly
without solver/jpeg/png/triangle/netgen/gsl support.

- clarify Combine commands
- explain the funcdamental difference between post-pro options and post-pro plugins

note for fltk 1.1.7

with node ordering corresponding to positive orientation (volume).
Test implemented for 1st and 2nd order elements, but only 1st order hexas
have actually been tested!

fix copy/paste: netgen->ann

simpler tetgen integration by Jozef Vesely
