%%%This patch is a quick implementation of the proposal, to get working physics constraints for group instances.

The complete proposal an implementation description:
https://gitorious.org/bge-sandbox/pages/GroupCons

Some files for testing ragdolls, and the common constraints from the regression files:

%%%cleanup:
With the newer patch, a function for the constraint setup is created, that is used in the scene converter routine and also in KX_Scene class to avoid code duplication.
Some changes to sconscripts and header includes are made to get this to work.

what was tested so far:

instantiating groups with constraints via add->group instance
instantiating groups with constraints via python game engine api addObject()
instantiating groups with constraints via edit object actuator -> add object
instantiating groups that are loaded on inactive layers with LibLoad function

for using groups with constraints as a library there are some restrictions at the moment.

objects with constraints have to be created on inactive layer
objects with constraints have to be instantiated on inactive layer, these objects could then be loaded with LibLoad and then added via addObject/actuator
only working with "Scene" mode for LibLoad

%%%Thanks for the patch,

I had a first look, I see no problem with it. I'll have a second closer look in the coming days.

%%%I really don't like the CcdPhysicsEnvironment.h include in BL_BlenderDataConversion.h. KX_Scene should not have to access Bullet directly, this defeats the purpose of encapsulating the physics library.%%%

%%%I made a bug fixed from the last patch.

Change list:

Added the missing paths in the makefile.
Fixed. Don't add constraints for Objects on inactive layers.
Fixed crash after deleting and adding a new object with constraints.
Fixed replicated objects are replicated the constraints on the target object instead of the source object.
Fixed implicit cast in setup_constraint4object.
Add missing documentation for getParent, setParam, constraint_id.
Add a function to get the constraint form Blender generated constraints.
Add attribute to get the constraint type.

group-constraints7_HG1.patch with [#36388] Delete recursive DupliGroup objects.
group-constraints8_HG1.patch
