more work on polyhedra

more work on levelsets & co

- make sure we don't package the binary dir in make package_source
- fix GMSH_VERSION in Info.plist
- move last few README to README.txt
- added all remaining un-committed converters from mailing list into utils/

- 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

Bugfixes around the place.

Changed GMSH_LIBS order in configure.in in order to make linker work with
homology computation plugin under linux.

Added more message console info about homology computation.
