Walk on Same Type Dynamical Agent

After version 3.2, we re-build the interal collision detection and dynamic scene query machanism, 

Now the agent with CCT can walk on the same type of agents which enabled dynamics.

Such as below picture shown, the front spiders have been shot dead and enable dynamics, and the same type of spider walk on their bodies.

The only thing we need to setup is enable the spider "CCTColide" attribute on the "agent group" node.

And the other things are all automatically.
