• [kinetic] deprecated syntac in transmission hardware interface cob_simulation#150

[ WARN] [1499671498.320796292, 0.162000000]: Deprecated syntax, please prepend 'hardware_interface/' to 'PositionJointInterface' within the <hardwareInterface> tag in joint 'XXX'.

needs to be adjusted in the joint's transmissions e.g. https://github.com/ipa320/schunk_modular_robotics/blob/indigo_dev/schunk_description/urdf/common.xacro#L45-L57
However, this is currently not dual-distro compatible with indigo

@fmessmer FYI

fixed in #216
