Removes the boilerplate comments, unnecessary link_directories()
and fixes up the dependency declaration (proper catkin and system
dep listing) in CMakeLists.txt.

Related changes are made to the manifest.

Note: catkin_lint still complains about 'boost' being unconfigured,
      but this seems to be due to a difference in capitalisation
      between the CMake Findscript and the rosdep entry.

Must set flag to activate fix now.

Moveit plugin works, but kinematics incorrect.  Old kinematics description
is probably inaccurate.

Updated to catkin.  ur_driver's files were added to nested Python directory for including in other packages.

Ported ur_kinematics package from Georgia Tech library.  Added ability to create ur5 & ur10 kinematics libraries.  Python libaries not untested.  Kinematics still needs to be wrapped within Kinematics plugin interface
