Subject: * Applying Nlin's NINJA Joint patch. v2.   Mantis# 2874 * Thanks
 nlin! * To try it out, set ninja joints active in the ODEPhysicsSettings and
 use the example at: *
 http://forge.opensimulator.org/gf/download/frsrelease/142/304/demo-playground.tgz.
 * Don't forget to change the .tgz to .oar and load it with load-oar.
