Allow i3wsr compatibility

[GallaisPoutine]

Moving from i3wsr to swaywsr, two options syntax in the toml configuration file have changed.

no_names --> no-names

Allow to use the same syntax on i3wsr for those options so that near zero changes have to be made to switch to swaywsr in the config file.

Do not hesitate to tell me if you also want me to update the documentation.
