Only create the tessface layer if it does not exist.

Use tangent generation code in game engine.

Tangents are now taken into account when generating tangents for
rendering - Normal maps work again.

Added special code that only creates a tessface layer for tangents, also
added code that creates tangent mface data from loop data during mesh
conversion.
