Add 18.04, use more packages from robotpkg, and update devel

[nim65s]

Hi,

This PR:

• use robotpkg binaries for osg-dae, baxter-common & romeo-description
• fixes the ROS_PACKAGE_PATH to do so in config.sh
• updates some changes in devel branches, like
  • gepetto-viewer needs the PROJECT_USE_QT4 flag
  • gepetto-viewer-corba don't need it anymore, and uses the one from gepetto-viewer
  • hpp-corbaserver needs hpp-template-corba
• adds 18.04 support with:
  • a Dockerfile and a Dockerfile.premade
  • new jobs (allowed to fail for now) in the .gitlab-ci.yml
  • a config.sh
  • a case switch in auto-install-hpp.sh
• while here, update the cmake submodule

Everything (with the only exception of https://github.com/humanoid-path-planner/hpp-rbprm/issues/31 ) looks good on 16.04. On 18.04, I already corrected a few minor things, but more work is still required here and there.
