Added support for multiple UVs in the render engine. This also involved changing the way faces are stored, to allow data to be added optionally per 256 faces, same as the existing system for vertices. A UV layer can be specified in the Map Input panel and the Geometry node by name. Leaving this field blank will default to the active UV layer. Also added sharing of face selection and hiding between UV layers, and at the same time improved syncing with editmode selection and hiding. Still to do: - Multi UV support for fastshade. - Multires and NMesh preservation of multiple UV sets.
