tsched=0 PA config for meiousei
Conditionals in xinitrc for tsukikage/meiousei

asd.service and nvidia-settings are now in a conditional so
not-tsukikage doesn't complain.

pulseaudio is launched with meiousei.pa for meiousei (imagine that!).
I should be able to extend that to all hostnames later on, if needed.

TIL $HOSTNAME is a bashism. *sob*
