Learning Blender 2.5 tutorial update

[kat]

I've just updated the Learning Blender 2.5 tutorial so the section discussing the assignment of multiple materials to the chair mesh now shows what the end result would be like with the appropriate textures assigned to the objects UVW map. To accompany this, a new *.blend file ("18b") has been included in the resource archive. An updated version of the PDF should be available soon once the old format has been amended.
