Onefeel:
- Modified onelab options (activated through --onelab.enable=1 and not anymore with --generate-ol)
- Added new python script (easier normally)
- Added mpi support
- Added remote host support
- Added schroot support
(Everything still needs some testing and requires Gmsh patches, notably for mpi, chroot and remote host support)
