Cycles Hair: Addition of render settings and static BVH strand width scaling
Addition of a RNA function to toggle between the hair settings and rebuild the cache. This enables the usage of the render step, child number and full display percentage with f12 rendering.
A scaling to the strand radius has also been added for the static bvh. This only matches up with dynamic for uniform scaling.
A very small fix is included for multiple uvs/vertex colours when using child particles.
