Random Event Antag Prompt should tell you what Antag it is

[Flaborized]

This is a good idea and also feasible because currently it picks the antag before/when it polls dead people, not after. (I know this because the admin notification for the random event says what kind of antag it will be when it sends the poll). It'd be better if you knew what antag you were getting instead of it being a shitty gamble between fun time and not fun time if you don't like one of the potential results
