* Added CBillboardGroupSceneNode to the make file

* whoops, missing CBillboardGroupSceneNode.cpp

* Should fix missing tree references.

* setting *nix makefile eol-style native

* Fix case error in CSceneManager.cpp for EMaterialTypes.h

* Committing more memory management enhancements to IrrlichtNETCP

Fixed up some methods for speed and memory in IrrlichtW/NET
* Don't keep a reference to the Vertex3D that we're changing the color for.  We have no use for it anyway.
* Added a way to loop over the vertex in the Mesh buffer in C++ so that it's speedy.

* Adds IntPtr MeshManipulator_CreateMeshCopy(IntPtr mm, IntPtr Mesh) which hooks to the native method.  Use this to reduce your Vertex3D references if you build your own mesh.

* Add the goofy messed up texture transform logic.  It's evil, evil, evil..    but I guess they can't fix it?

* Updates Irrlicht to use Klasker's trees as a 'default' object.
* Introduces a memory leak, however with the CTreeGenerator.   Will fix this.

* Updates Irrlicht's include files for the AddTreeSceneNode changes so that IrrlichtW can hook to them.

* Updates IrrlichtW so that you can call SceneManager_AddTreeSceneNode to make one of Klasker's trees.

* Adds a TreeSceneNode from Klasker as a standard object that you can add to the scene from the SceneManager.   it ends up as a Scene Node currently.  Might make a specific SceneNode in the future to add some tree specific methods.

* Various updates to IrrlichtNETCP so ambient light works again.

* Recommit Freetype so IrrlictW builds

IrrlichtNETCP updated to work with Latest Irrlicht Trunk as of this date.  r1686.
