The ros-comm 1.9.53 now also contains the new package rosbag-storage.

The ros-comm recipes are updated to 1.9.50 to be in line with
https://github.com/ros/rosdistro/blob/ef3a7449d7f7ef6e691a5724ef6c485e75cfd4af/hydro/release.yaml.

The native packages are not required anymore, because the needed
python scripts during compile time are also provided by the
cross-compiled packages and the python scripts are platform
independent. Only the catkin package is provided as native package.

The ros-comm recipes are updated to 1.9.48 to be in line with
https://github.com/ros/rosdistro/blob/4551e7c32d1b34984410b79bc0ec36afe3d3d245/hydro/release.yaml.
The previously applied patches have been included in 1.9.48 and are
removed from the recipe and this repository.

All ROS packages with install tools in the bin directory or install
python code with is used by other packages should be used as native
