First set of changes to port to Hydro. Changed files to catkin build system. Changed code of the plugin to address changes in ROS <-> PCL cloud conversion. Now it is sensor_msgs <-> pcl::PCLPointCloud2 <-> pcl::PointCloud2. The plugin for some reason cannot be loaded by V-REP, and so YouBot topics are not available.
