Disable border on inactive windows variable

[olavorw]

Describe the feature

A config item (bool) which would let users disable inactive windows' borders. You can kind of makeshift it by setting col.inactive_border to none but that results in a kind of weird transparent useless border which also messes up shadows so it doesn't really count. This also doesn't work with windowrules as if you do ar ule where the focused window gets a bordersize of 2, the windows behave badly and when changing the focused window to a different one everything shifts up and down for a couple seconds and so that's broke.

Why would it be beneficial

To make inactive windows appear more elegantly and give users a choice to not to even have a border over non-active windows.
