Adds zipties

- Identical to cablecuffs except they break after use
- Beepsky and sec borgs use these by default now
- Beepsky and sec borgs have been stealth nerfed sorta (their cuffs take half the time to take off since they're zipties now!)
- Added some to sectech for robust officers
- Warden spawns with a box in his locker (warden needs zipties the most since all he does is bucklecuff)
- Removed renamed cableties on nuke op shuttle and replaced with a box of zipties if syndies want to be high speed low drag and restrain civvies or kidnap the clown
- Moved a few stools around on the nuke op shuttle to make things look better

If you want zipties to act like cablecuffs, why are you not making the path /obj/item/weapon/handcuff/cable/zipties.
