IBillboardSceneNode got functions to access meshbuffers.

So uv-coordinates can now be modified directly (previously only possible via texture matrix).

 --------------------------\r
 Changes in 1.9 (not yet released)\r
+- IBillboardSceneNode got functions to access meshbuffers. So uv-coordinates can now be modified directly (previously only possible via texture matrix).\r
 - vector3d scalar operator/ and operator/= no longer multiply by the inverse but use the expected division. \r
   Costs some speed, but fixes floating point troubles caused by this optimization (like x/x no longer being 1.0).\r
 - Add equals and set_data functions to core::array for easier working with blocks of data.\r
