Sas control mods update

[Clamp-o-Tron]

Unfortunately, KSP doesn't allow mods to add new SAS modes to the navball interface, at least in the panel where the stock SAS modes show up. (I'm pretty sure? Correct me if I'm wrong and there's a way to do it). The best alternative is Throttle Controlled Avionics by @allista. That only covers some stuff, so there's no way for now to get other directions, like pointing for max solar panel efficiency.
