+    Use Joint::SetParam for joint velocity motors
+    
+    Before gazebo5, Joint::SetVelocity and SetMaxForce
+    were used to set joint velocity motors.
+    The API has changed in gazebo5, to use Joint::SetParam
+    instead.
+    The functionality is still available through the SetParam API.
+    
+    cherry-picked from indigo-devel
+    
+    Add ifdefs to fix build with gazebo2
+    
+    It was broken by #315.
+    Fixes #321.
