Waybox 0.0.1

Version 0.0.1 of Waybox, an Openbox clone for Wayland, is available. At this stage, it's basically just mcwayface, but it'll compile with wlroots versions 0.1 through 0.8.1, where mcwayface won't (mcwayface would compile with some pre-0.1 snapshots of wlroots, but it wouldn't by the time wlroots 0.1 was released). Waybox 0.0.1 won't compile with wlroots 0.9 and higher due to an incompatible change introduced in wlroots 0.9, meaning the output-rendering code has to be completely rewritten for wlroots 0.9+.
