Removed the "support more hardware interfaces" line.
Added support for the position hardware interface. Completed support for the
velocity hardware interface.
Gazebo ROS joint state publisher added
gazebo_ros_diff_drive was enhanced to publish the wheels tf or the wheels joint state depending on two additinal xml options <publishWheelTF> <publishWheelJointState>

gazebo_ros_control now depends on control_toolbox.
Position-controlled and velocity-controlled joints now use PID controllers
instead of calling SetAngle() or SetVelocity(). readSim() now longer calls
angles::shortest_angular_distance() when a joint is prismatic.
PLUGINLIB_EXPORT_CLASS is now used to register the plugin.

Merge from upstream
Merge remote-tracking branch 'origin/hydro-devel' into camera-info-manager
joint->SetAngle() and joint->SetVelocity() are now used to control
position-controlled joints and velocity-controlled joints that do not
have PID gain values stored on the Parameter Server.

gazebo_ros: remove assignment to self

If this is needed for any twisted reason, it should be made clear
anyway. Assuming this line is harmless and removing it because it
generates cppcheck warnings.
gazebo_ros: [less-than-minor] fix newlines
joint velocity fixed using radius instead of diameter
Removed some debugging code.
