Zipline gadget for safeguarding entry/distractions

A gadget for either clearing a zipline landing zone, or creating a smoke trail along the zipline before using it. One per map, can be picked up by intruders and set onto a zipline. If you left click to hook gadget onto zipline, it uses an explosive mode, wherein the hook will immediately move down the zipline and detonate once it falls off at the end - ragdolling any enemies in the immediate landing vicinity. Right clicking sets the gadget into smoke/vapour mode, wherein it will move down the zipline, leaving a short-lived smoke trail behind it to obscure enemy vision of the line. The gadget can be destroyed by shooting it, and could have a bright colour scheme and a blinking light to indicate its position on the zipline for night-time maps.
