Some users may want to switch buttons on their input devices, turns out
libinput already supports it. Let's add a support for it in our config.

Add swayc_change_layout function, which changes either layout or
workspace_layout, depending on the container type. Workspace being
always L_HORIZ makes this much more i3-compatible.
This implements commands such as:
workspace number 9: test
If a workspace with the given number exists then it will be focused,
otherwise a new workspace with the given name will be created.
