Impostor role: Bomber

[Anusien]

There's a new impostor role: the Bomber. In addition to a normal kill button, they have the opportunity to place a bomb. You place a bomb by targeting another player (presumably a non-impostor player) and activating the button. 5 seconds after the bomb is placed, the bombed player gets a flash on their screen, a 20 second countdown and a new kill button. If they don't use their new kill button to kill somebody within that timer, they die. Successfully killing somebody within that time frees them. Attempting to kill the person who originally bombed you kills you. Attempting to kill the impostor's partners succeeds.

Questions:

• Should the bombing reset the normal kill cooldown?
• Should planting a bomb take some amount of time next to them/standing still? (Probably not for now)
• Is there a better name than bomber?
• What happens if you attempt to kill a shielded player?
• Should the bombed player be able to report their kill?

Inspired by the similar role in 5up's mod.
