The xdg-decoration protocol allows clients to request whether they want to use server side decorations or client side decorations. Currently, sway ignores this and always enforces whatever the server is currently set to. Although tiled clients cannot be allowed to set borders, there is no harm in listening requests from floating clients. Sidenote: also fix an unrelated style error.
