basics+bspwm+herbstluftwm+i3wm+meta+polybar+xmonad: wm configs overhaul

Created polybar as its own config instead of duplicated in bspwm and
i3's directories allowing them both to be installed.

Created herbstluftwm, xmonad window manager configs.

Added scripts for a status bar, and fixed scripts.
