Provide a way for out-of-tree users of lualoader to patch into the loader system without having to modify our distributed scripts. Do note that we can't really offer any API compatibility guarantees at this time due to the evolving nature of lualoader right now. This still has some utility as local modules may add commands at the loader prompt without relying heavily on lualoader features- this specific functionality is less likely to change without more careful consideration.
