New option "move texture channel up/down" lacked redraw calls. Featurette: There's still no manipulator handles for lamps to set cone size, dist, clipping. To save our poor Peach artists hours of work I've added a quick method to at least be able to do it interactive. Option is hidden behind Wkey, and uses a similar function like Scaling. (Put mouse cursor close to start value, move mouse to center of lamp) Ultimately this should move to custom manipulator handles...
