added a function to duplicate bPoseChannel's internal data - constraints, id-props etc.

 duplicate_pose_channel_data(), the code to do this was inline in editarmature.c

duplicating editbones now duplicates posebone id-props

also removed an if test for &channew->constraints since it will always be true.
