- Makes `tree_next` not recursive. - Adds `focus next|prev [sibling]` command. See (1.) and (2.) in https://github.com/i3/i3/issues/2587#issuecomment-378505551 (Issue also requests move command, not implemented here). - Directional focus command now supports command criteria. Wrapping is not implemented inside a floating container. This was also true before the refactor so I am not changing it here.
