~/.xinitrc: Fullscreen-friendly taffybar.

Somehow when started manually (i.e. after xmonad) it's actually on top
of it, which is not what I want. So I'll just start it before xmonad
itself and all is well.

I still wonder whether this is normal behaviour.

.xinitrc

#xmodmap ~/.swap-esc-capslock
synclient TouchpadOff=1
taffybar&
#exec awesome
exec xmonad
#exec gnome-session
