While Wayland offers nothing general to help us support `focus` on all window managers, WM-specific implementations are generally possible. Sway is a tiling window manager that mimics i3, and has a reasonably powerful CLI that can help us achieve this. In addition to supporting `focus` for Sway, this change paves the way for additional WM-specific Wayland functionality by adding a detection step to wayland.kak, in a similar fashion to detection.kak.
