polybar: Use inheritance for bars
polybar: Use inheritance for bars

Maybe this is a new feature of polybar, or maybe I've never read the
documentation thoroughly enough. This commit adds inheritance for my
floating bar and top bar, so that duplication isn't necessary.

This makes things a lot easier to see and understand. There is also a
way to include other files, which may be useful for automatically
generating key value pairs for polybar based on screen resolution.

It may also be used to set different variables (i.e. colors) based on
which bar is used. Pretty handy.
