Revert "Remove polybar"

I don't actually need to get rid of my old config files if I ever want
to have easy access to them in the future. Although I intend on using
Wayland, having a nice interface for traditional X applications may not
be a bad idea (some graphically intensive programs also run better there,
apparently).
