Some patches that make hydro-devel work with catkin_make_isolated

When each package is built and installed separately (e.g. with catkin_make_isolated), header files that are also needed by dependent projects need to be installed as the devel or source space is not accessible. I guess this is also what the ROS buildfarm would do.

5d69810 is more or less a bugfix. I guess there have been some file renamings recently. 0037592 adds an install rule for generated boost headers.

With these patches, rtt_ros_integration and rtt_common_msgs compile successfully on my machine with `catkin_make_isolated --install`.
