Support multiple tangents for BI render & viewport
Normal Map node support for GLSL mode and the internal render (multiple tangents support).
The Normal Map node is a useful node which is present in the Cycles render.
It makes it possible to use normal mapping without additional material node in a node tree.
This patch implements Normal Map node for GLSL mode and the internal render.
Previously only the active UV layer was used to calculate tangents.
