Remove traits from afterlife bar spawners, and possibly give them the radio brain mut

[Zamujasa]

Players who choose the "deaf" trait are unable to hear anything in the afterlife bar because they do not get the auditory headset, rendering the afterlife bar mostly off-limits.

Additionally, afterlife bar patrons have no way of hearing what's going on on the station; the radio brain mutation allows them to hear (but not speak to) the main station channel, so they can at least remain somewhat aware in their afterlife.

I'm cool with this.
