Make reaction roles for discord roles like Zombies and Vote

DG discord suggestion

in #info or #rules message, and if u react with like :regional_indicator_z: you get Zombies role (with dyno)

:regional_indicator_v: - vote
:regional_indicator_s: - survival
:regional_indicator_p: - pvper

(i forgor last one)

I’ve already suggested something like this internally, so you have my support on this one
