requires the pcl library.

While adding image-geometry, the common part to cv-bridge was put
into the vision-opencv.inc file.

ros_control recipes

Initial recipes for image_transport_plugins (resolves #136)

The ROS package cv_bridge needs the Boost.Python library. This
commit adds a bbappend file that includes Boost.Python in the
boost recipe using PACKAGECONFIG.
This PACKAGECONFIG for boost is available since commit
7568bfdd114597956a1da68746f207ec7f93a48d
in the openembeddded-core repository [1].

removing roscpp patch and adding actionlib-tutorials recipe

After the native packages are removed, the roscpp patch, which was
originally required for dynamic-reconfigure-native, is not needed
anymore.

updating and simplifying recipes (#160 and #139)

When CATKIN_ENABLE_TESTING is deactivated, the ROS packages do not
require the rostest package.
This commit includes a number of patches to be submitted in the
upstream repositories and removes the rostest dependencies from
the recipes.
