Got the prismatic joint connected up to use the OSG layer to draw it.
Also, fixed a bug that I had in the hinge joint drawing code.
Removed the reference to VsFreeJoint.h
Moved the attachment and the free joint over to be under the osg layer.
Moved over the OsgOdorSensor and OsgMouth. I also moved everything into the appropriate namespaces.
Merge branch 'master' of https://github.com/NeuroRoboticTech/AnimatLabPublicSource
Modified the vortex unit test to create a sim object and use that to create a rigid body.
