ac3d loader - better sharing of states between objects and Roger James' bug fix for missing normals.

  Tesselator.cpp - faster processing of polygon tesselation for single triangles (which dont need to be tesselated)

  osgtesselate.cpp - added wrap for texture so that appearance is as originally. Default texture behaviour has changed to clamp."
