fixed typo
Removed need for our own republisher.

Instead relying on robot_pose_publisher which was designed to do this explicitly. See: https://github.com/WPI-RAIL/nav2djs/issues/26#issuecomment-20123090
Made this a valid catkin package.
Merge pull request #23 from hawesie/master

Use robot_pose_publisher instead of the republisher I wrote. Also made this a valid catkin package.
