Added launch directory to bringup package.  Left the old launch files to be backwards compatable for now.  Updated driver with SwRI internal changes.  Changed driver to accept ip address to match ROS-Industrial standard.  IP addresses for industrial robots are typically fixed.  Hostnames are not typically used (this is what the driver expected)
Updated urdf files use collision/visual models.
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
