Add new cube mesh type ECMT_1BUF_24VTX_NP. CubeSceneNodes can now use different cube mesh types.

Browse Source 
1 Meshbuffer with 24 vertices, so each side has it's own vertices.
Normals perpendicular to the cube-sides.
CubeSceneNode accepts now a ECUBE_MESH_TYPE
CubeSceneNode::clone now also clones rotation and scale (not sure why it didn't do that before - hope there was no reason, but can't think of any).
ISceneManager::addCubeSceneNode accepts now a ECUBE_MESH_TYPE and passes it through.
Example 22.MaterialViewer using new cube type. Also a few more beauty fixes there.
