updating ur driver to support UR10 and cleanup in packages
Reorganized meshes to include both collision and visual messhes (like other ROS-I robots).  Modified urdf xacro to include new models.  Removed extra robot pedestal link from urdf (urdfs should only include the robot itself).
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
Added ur5 moveit library.  The Kinematics used by the ur5 move it library is unreliable and should be replaced with the ur_kinematics
Added joint limited urdf and associated moveit package.  The joint limited package is friendlier to the default KLD IK solution
Added readme file describing the differences between move it packages
Removed ur5_joint_limited_moveit_config.  ur5_moveit_config now has limited joint ranges to plus/minus 180 degrees.
Removed readme that explained differences between move packages
Merge pull request #5 from ros-industrial/swri_internal_mods

Swri internal mods
Create README.md
converted tabs to spaces
prefix versions of gazebo and transmission macros
merged ur10 description from GT
added collision model for ur10 base
Added launch/configuration files for using real robot.  Updated joint limits to velocity limits of the driver (all of which can be configured to make the robot move faster)
Added config files missed on last commit
