- fixed the "unix socket name is one character short" problem on
MacOS and AIX. Unfortunately, this required the client code to be
slightly modified as well (and as a consequence, old versions of getdp
will for example not work with new versions of Gmsh on MacOs and
AIX). But it's better to do things "the right way" (TM) for people who
want to connect using different languages (Perl, Python).

- moved the GmshServer stuff in its own class

- added missing rules in parser makefile (so that the parser gets
  rebuilt automatically when one changes Gmsh.y or Gmsh.l)

reorganized solver directory + added c++ solver example

remove extra test on !port

The TCP patch broke UNIX solckets on Winwows (since Windows paths can
contain a colon)

pretty print

contrib

Support for TCP/IP sockets (permits to launch solvers on remote hosts).
Thanks to C.Stott@surrey.ac.uk for the original patch.

Small changes inspired by Wednesday's discussions:

- Mac only: Gmsh now publishes its "file types"... That means that
  geo/msh/pos files now have nice icons, and that you can double-click
  on a geo/msh/pos file in the Finder to open it :-)

- removed support for fltk 1.0 (wasn't compiling anymore anyway)

- doubled the timout in GmshServer (2->4s): this seems to help on
  Windows (thanks to jkools@veeco.com)

- added warnings in the docs about the Attractor feature

- increased WB by 1 pixel in the GUI

- replaced more Msg(FATAL) with Msg(ERROR) where it makes sense

Update copyright notice

Move the client/server code to a more permissive X11-like license

Changed license to LPGL (GPL doesn't really make sense for this file,
since we don't want to prevent non-free solver clients to be
interfaced with Gmsh)

Reorganized utils/ directory + added Maya converter from
<kenny@diku.dk>

Fix whitespace in copyright headers

Indented all source files using utils/gmshindent

Updated copyright
