Give the rebuildable reward designs unique touches

Rewards whose look the basic designs can build now carry a touch the builder cannot make: bursts on jumping, landing or sneaking, footprints, a line to nearby players with the same reward, a December extra, aimed enchanting glyphs, a heartbeat, a jump-beat wing or an orbiting shape. BodyMotion tracks the jump, land and sneak events the touches react to.
