[ros-release] Sync from shadow to fix ros-gazebo-pkgs

Hi all:

Since we released gazebo-2.0.0 (breaking API/ABI) the current versions of
ros hydro packages (< 2.3.3) are not working for the users using the
standard apt-get method. See: http://answers.gazebosim.org/question/4630

ros-gazebo-pkgs 2.3.3 is ready in shadow-fixed since a couple of days ago
and should fix the problem. Any chance of getting them into official ros
any time soon? What is the expected time for the next release of hydro
packages?

Thanks.
