Update nuclear bomb's regular and hacking UI to NanoUI

Changes:
1. Changes the nuclear bomb's regular and hacking UI to NanoUI.
2. The end of round message now distinguishes between the bomb being on station, off station (as in, far from the station but on z-level 1) and on another z-level. While the code previously did take this into account, the message would always be the same.
3. Fixed an HTML injection exploit in the nuclear device code (ported from /tg/).
4. The Emergency Response Team now spawns loyalty implanted.
