sbpl_lattice_planner: updated sbpl_lattice_planner to compile with the new costmap_2d package in hydro (DRAFT!)

Not sure if the clearRobotFootprint() call is still needed or if this is handled by the footprint layer...
sbpl_lattice_planner: add target dependency to sbpl_lattice_planner_generated_messages_cpp
sbpl_lattice_planner: do not copy Costmap2D instance and remove
clearRobotFootprint() calls

sbpl_lattice_planner: try to fetch possbily circumscribed radius from inflation layer
