assisted_teleop: link to trajectory_planner_ros explicitly (not exported by package base_local_planner)
deleted rosbuild stack files (CMakeLists.txt and Makefile)
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...
